Book Synopsis Design and Modelling of Electronic Processing Circuits for Optical Code Division Multiple Access Communication Networks by : M. N. Pimenta
Download or read book Design and Modelling of Electronic Processing Circuits for Optical Code Division Multiple Access Communication Networks written by M. N. Pimenta and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Code Division Multiple Access (CDMA) has been proposed for optical fibre networks to a achieve high-speed connectivity, asynchronous operation and network control simplifications. Traditionally, all-optical devices have been proposed to encode, decode and process CDMA signals because the bandwidth in the optical medium is higher than electronic processing techniques. Today's advances in integrated circuit technologies coupled with bandwidth efficient circuit topologies, may provide robust alternatives for CDMA over fibre applications. This thesis overs two areas of work. First, a new circuit for encoding and decoding incoherent CDMA signals in the electrical domain is proposed. This structure makes use of the high bandwidth of distributed amplifier-like topologies to achieve very wideband operation. As proof of concept, a distributed transversal filter was designed with a commercial available GaAs MMIC process; modelling results show feasibility of CDMA encoding/decoding at 40 GChip/s employing transistors with cut-off frequencies of 60 GHz. Limitations and potential practical applications of these design ideas are discussed. The second part of the thesis focuses on the impact of the time skewing due to optical-fibre Group Velocity Difference in Wavelength-Hopping Time-Spreading (WHTS) Optical CDMA and the compensation of this impairment through electronic techniques. A new network model was created to assess the impact of such impairment in these systems. Conclusions about the time skewing impact on the auto and cross-correlation properties of the system are extracted. This model was employed to assess the use of an electronic distributed transversal filters as time skewing compensator in Optical CDMA networks. Finally, an experimental setup of a WHTS Optical CDMA network was built to analyze the effect of time skewing and to assess the practical feasibility of its compensation with a distributed transversal filter. The Fiber Bragg Grating based system comprises 2.5 GBit/s transmission (20 GChip/s) with five wavelengths. Conclusions about the practical limitations are derived and presented.

Book Synopsis OFDM and MC-CDMA for Broadband Multi-User Communications, WLANs and Broadcasting by : Lajos Hanzo
Download or read book OFDM and MC-CDMA for Broadband Multi-User Communications, WLANs and Broadcasting written by Lajos Hanzo and published by John Wiley & Sons. This book was released on 2005-01-28 with total page 1014 pages. Available in PDF, EPUB and Kindle. Book excerpt: Orthogonal frequency-division multiplexing (OFDM) is a method of digital modulation in which a signal is split into several narrowband channels at different frequencies. CDMA is a form of multiplexing, which allows numerous signals to occupy a single transmission channel, optimising the use of available bandwidth. Multiplexing is sending multiple signals or streams of information on a carrier at the same time in the form of a single, complex signal and then recovering the separate signals at the receiving end. Multi-Carrier (MC) CDMA is a combined technique of Direct Sequence (DS) CDMA (Code Division Multiple Access) and OFDM techniques. It applies spreading sequences in the frequency domain. Wireless communications has witnessed a tremendous growth during the past decade and further spectacular enabling technology advances are expected in an effort to render ubiquitous wireless connectivity a reality. This technical in-depth book is unique in its detailed exposure of OFDM, MIMO-OFDM and MC-CDMA. A further attraction of the joint treatment of these topics is that it allows the reader to view their design trade-offs in a comparative context. Divided into three main parts: Part I provides a detailed exposure of OFDM designed for employment in various applications Part II is another design alternative applicable in the context of OFDM systems where the channel quality fluctuations observed are averaged out with the aid of frequency-domain spreading codes, which leads to the concept of MC-CDMA Part III discusses how to employ multiple antennas at the base station for the sake of supporting multiple users in the uplink Portrays the entire body of knowledge currently available on OFDM Provides the first complete treatment of OFDM, MIMO(Multiple Input Multiple Output)-OFDM and MC-CDMA Considers the benefits of channel coding and space time coding in the context of various application examples and features numerous complete system design examples Converts the lessons of Shannon’s information theory into design principles applicable to practical wireless systems Combines the benefits of a textbook with a research monograph where the depth of discussions progressively increase throughout the book This all-encompassing self-contained treatment will appeal to researchers, postgraduate students and academics, practising research and development engineers working for wireless communications and computer networking companies and senior undergraduate students and technical managers.

Book Synopsis Optical Code Communication in Local Networks by : Bas Huiszoon
Download or read book Optical Code Communication in Local Networks written by Bas Huiszoon and published by LAP Lambert Academic Publishing. This book was released on 2010-06 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: The continuing growth in Internet services and the associated bandwidth consumption presents many challenges to be met at the network tiers. The deployment of a fiber-optic local network is important because as soon as it is in place, it provides broadband access to the Internet cloud. In this book, such architecture is envisioned to be moderate in costs and complexity through sharing of resources, simplified nodes at the user-side, and centralized network management. The provisioning of wireless networks and, consequently, the handling of mobile networking dynamics is considered to be essential to enable truly ubiquitous networking possibilities so the convergence of the optical and the radio domains has a central position in the book. The optical code division multiple access (OCDMA) technology serves as basis on top of which many networking concepts are evaluated. A unique insight is given in the complete trajectory of OCDMA system design from modeling, to photonic integration, until full-scale transmission experiments. This book is intended for (under-) graduate students and system designers in the area of fiber-optic local networks.
