Available in PDF, EPUB and Kindle. Book excerpt: To keep pace with the rapid expansion in data-exchange traffic around the world, optical networks are anticipated to provide flexibility to maximize utilization of the deployed optical fiber resources. On the other hand, digital signal processing (DSP) has been employed in coherent optical systems to enable 100G and beyond optical fiber networks. The goal of the thesis is to develop advanced DSP techniques for the flexible optical networks. With the reconfigured modulation formats in the systems, modulation classification (MC) is essential in the DSP to facilitate the sequential compensation modules which are modulation format-dependent. Based on the cumulative distribution function (CDF) of received signal's amplitude, an MC algorithm for M-ary quadrature amplitude modulation (M-QAM) formats with M = 4, 8, 16, 32, and 64 is proposed. Results show that the proposed algorithm achieves accurate classification at optical signal-to-noise ratio (OSNR) of interest and is robust to frequency offset and laser phase noise. Relying on the CDF of received signal's amplitude, a non-data-aided (NDA) OSNR estimation algorithm is developed for coherent optical systems employing multilevel constellations. It outperforms the state-of-the-art NDA algorithm in terms of performance and complexity. Furthermore, a joint OSNR estimation and MC algorithm enabled by support vector machine is designed. Compared to deep neural network-based joint estimation approach, the proposed algorithm achieves better performance with comparable complexity. In addition, a low-complexity two-stage carrier phase estimation algorithm is proposed for coherent optical systems with 16-QAM format. The proposed algorithm exploits the second power operation instead of the conventional fourth power to remove the modulation phase, which is enabled by constellation partition and rotation. Optical back-to-back experiments and numerical simulations are carried out to evaluate the performance of the algorithm. Results show that, compared with the conventional fourth power-based CPE algorithm, the proposed algorithm provides comparable tolerance to the carrier phase noise, with reduced complexity. Lastly, a novel transmission scheme is investigated for the open and disaggregated metro coherent optical networks, which impose the requirements for multiple user connectivities on the limited orthogonal frequency resources. Thus, it is desirable to provide connections simultaneously to various users in a non-orthogonal way. A transmission scheme based on the non-orthogonal sparse code multiple access in a digital subcarrier multiplexing is proposed. Compared to power domain-based counterpart, the proposed scheme supports more than 2 users without user pairing and clustering. The feasibility of the proposed scheme is verified through numerical simulations. Three scenarios with 2, 4, and 6 users over 1, 2, and 4 subcarriers, respectively, are considered. Performance evaluations show that in all scenarios, the proposed scheme attains bit error ratio lower than the forward error correction limits with the transmission ranges of interest in metro applications.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "To satisfy the explosive growth in global Internet traffic, the development of transmission links that not only have high-capacity but are also flexible, reconfigurable, and adaptive is imperative. The advents of high speed digital-to-analog and analog-to-digital converters, and recent progress in complementary metal-oxide-semiconductor (CMOS) technology has facilitated the development of optical transceivers relying on coherent detection and digital signal processing (DSP) for the compensation of fiber impairments. Next generation coherent optical networks are anticipated to further approach the Shannon limit and deliver 400~Gb/s or 1~Tb/s data rates per channel, while providing flexibility and agility to maximize the utilization of the network resources. This thesis explores novel system architectures and advanced DSP algorithms to fulfill these design targets. Currently, chromatic dispersion (CD) compensation and forward error correction (FEC) decoders are the major power consuming (more than 50%) blocks of a conventional transceiver application-specific integrated circuit (ASIC). This thesis presents the concepts and architectures of multi-sub-band (MSB) signaling for mitigation of CD, and eliminating the need for a CD compensating equalizer in reduced-guard-interval (RGI) orthogonal frequency-division multiplexing (OFDM) and single carrier systems. The performance of the proposed techniques are experimentally evaluated using a leading-edge optical long-haul transmission test-bed. It is shown that the MSB technique, in addition to the evidently lower computational complexity, allows for a highly efficient adaptive rate smart transceiver implementation with lower system overhead and simplified parallelism, while attaining the same or better transmission reach and performance as the conventional transceiver. This is due to its higher tolerance to fiber nonlinearity.With coherent technology and advanced FEC, it is known that the capacity of current fiber optic transmission systems is fundamentally limited by fiber nonlinearities. We have optimized the perturbation based nonlinearity compensation (PB-NLC) equalization scheme and proposed a novel adaptive nonlinear equalizer. The performances of the aforementioned DSP equalization schemes are numerically and experimentally studied. It is found that the optimized technique demonstrates lower computational complexity over conventional PB-NLC. In addition, the proposed adaptive nonlinear equalizer does not require prior calculations of perturbation coefficients and detailed knowledge of the transmission link parameters. It achieves comparable performance to the PB-NLC. Unlike previously studied adaptive nonlinear equalization techniques, our algorithm takes advantage of common symmetries, avoids replication of operations, and only uses a few adaptive nonlinear coefficients. Finally, its computational complexity is smaller than previously proposed adaptive nonlinear equalization schemes, which meets the requirements of next generation optical networks." --

Available in PDF, EPUB and Kindle. Book excerpt: "Next generation coherent optical transports for core networks are anticipated to further approach the Shannon limit for a higher fiber capacity by delivering 400 Gb/s or 1 Tb/s data rates per channel, and providing flexibility and agility to maximize the network resource utilization. This thesis looks into novel system architectures and digital signal processing (DSP) algorithms to fulfill those design targets. The single carrier and orthogonal frequency-division multiplexing (OFDM) modulation schemes are both potential candidates for the underlying transceiver architecture. We provide the analysis and investigation of the optical channel impairments for both systems in the context of >100 Gb/s transmissions with higher symbol rates and higher order quadrature amplitude modulation (QAM). With an increased accumulated chromatic dispersion (CD) for a single channel, the impacts of laser phase noise and fiber nonlinearities manifest new characteristics which are not evident in current 100G systems. We propose novel and energy-efficient DSP algorithms and system designs to increase laser linewidth tolerance and reduce nonlinear noise. The performances of the proposed designs are experimentally evaluated using a leading-edge optical long-haul transmission testbed, which was custom built for this thesis. The single carrier and OFDM systems are separately explored and compared, and it is shown that OFDM has certain multi-carrier advantages when a large accumulated CD exists. This result implies that the OFDM scheme may be a better option for next generation transceivers than the currently employed 100G single carrier transceiver scheme. In the last part, we concentrate on the design of flexible optical transceivers for future software-defined optical networks. The following novel techniques are proposed to achieve a full flexibility without increasing the cost: format-transparent DSP platform, agile bandwidth allocation, and continuous modulation format." --

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Enabled by coherent detection and advanced digital signal processing techniques, next generation optical networks embrace such characteristics as ultra high capacity, ultra long transmission reach, agile yet cost-effective. Digital linear filtering is an indispensable technique that facilitates the advancement of coherent optical transmission systems. Currently, most digital linear filtering techniques are employed for mitigation or compensation for linear impairments, such as chromatic dispersion compensation, channel equalization and spectrally efficient pulse shaping. This thesis explores the potential of digital linear filtering techniques for mitigating both linear and nonlinear impairments in the fiber-optic transmissions.Polarization division multiplexed (PDM) high order quadrature amplitude modulation (QAM) provides a spectrally efficient solution for coherent optical transmission systems. PDM technique uses blind equalizers for polarization demultiplexing. We propose the decision directed least radius distance (DD LRD) blind equalizer for coherent optical transmission systems. Compared to other equalizers, the DD-LRD equalizer is found to have good steady state bit error rate (BER), better tolerance to high speed polarization rotation, excellent inter symbol interference (ISI) tolerance and less sensitivity to initial conditions. Pulse shaping is traditionally utilized for increasing spectral efficiency. We propose a new family of pulses, called frequency domain root M-shape pulses (RMP), to mitigate Kerr nonlinearity in the fiber channel. Experimental and simulation demonstrations reveal that compared to the widely used root raised cosine (RRC) pulses, the RMP can significantly extend the transmission reach in standard single mode fiber based dispersion unmanaged links and most legacy links using various fiber types and dispersion maps. The enhanced nonlinearity tolerance of the RMP is attributed to the fact that the RMP put more energy contents in their higher spectral components and disperse faster in a dispersive medium. In comparison with other nonlinearity mitigation or compensation algorithms, the RMP filtering technique embraces the following advantages for next generation optical networks: computationally efficient, link configuration independent and modulation format transparent." --

Available in PDF, EPUB and Kindle. Book excerpt: The achievable information rates of optical communication networks have been widely increased over the past four decades with the introduction and development of optical amplifiers, coherent detection, advanced modulation formats, and digital signal processing techniques. These developments promoted the revolution of optical communication systems and the growth of Internet, towards the direction of high-capacity and long-distance transmissions. The performance of long-haul high-capacity optical fiber communication systems is significantly degraded by transmission impairments, such as chromatic dispersion, polarization mode dispersion, laser phase noise and Kerr fiber nonlinearities. With the entire capture of the amplitude and phase of the signals using coherent optical detection, the powerful compensation and effective mitigation of the transmission impairments can be implemented using the digital signal processing in electrical domain. This becomes one of the most promising techniques for next-generation optical communication networks to achieve a performance close to the Shannon capacity limit. This chapter will focus on the introduction and investigation of digital signal processing employed for channel impairments compensation based on the coherent detection of optical signals, to provide a roadmap for the design and implementation of real-time optical fiber communication systems.

Book excerpt: The growth of Internet traf?c in recent years surpassed the prediction of one decade ago. Data stream in individual countries already reached terabit/s level. To cope with the petabit class demands of traf?c in coming years the communication engineers are required to go beyond the incremental improvement of today’s technology. A most promising breakthrough would be the introduction of modulation f- mats enabling higher spectral ef?ciency than that of binary on–off keying scheme, virtually the global standard of ?ber-optic communication systems. In wireless communication systems, techniques of high spectral density modulation have been well developed, but the required techniques in optical frequency domain are much more complicated because of the heavier ?uctuation levels. Therefore the past trials of coherent optical modulation/detection schemes were not successful. However, the addition of high-speed digital signal processing technology is the fundam- tal difference between now and two decades ago, when trials of optical coherent communication systems were investigated very seriously. This approach of digital coherent technology has attracted keen interest among communication specialists, as indicated by the rapid increase in the pioneering presentations at the post-deadline sessions of major international conferences. For example, 32 terabit/s transmission in a ?ber experiment based on this technology was reported in post-deadline session of Optical Fiber Communication Conference (OFC) 2009. The advancement of the digital coherent technologies will inevitably affect the network architecture in terms of the network resource management for the new generation photonic networks, rather than will simply provide with huge transmission capacity.
