Available in PDF, EPUB and Kindle. Book excerpt: Orthogonal frequency division multiplexing (OFDM) is a modulation technique which revolutionized the field of communications and paved the way for the modern-day 4G LTE communications. OFDM technique is used in both wired and wireless communications. This type of modulation technique offers low intersymbol interference and provides high data rates. Due to these advantages of OFDM it is used in various applications like 4G LTE communications, wireless networks and digital TV. Besides these advantages, a major disadvantage of OFDM system is high peak to average power ratio due to addition of sinusoidal waves in communication which result in peaks in the output and cause signal degradation. In order to reduce the PAPR, a hybrid technique which combines Hadamard transform and Hamming peak windowing is developed. This technique is compared with the PAPR results obtained for OFDM, Hamming windowing, and companding. The bit error rates of all the above methods are compared passing the OFDM signal through AWGN (additive white Gaussian noise) channel.

Book Synopsis Hybrid PAPR Reduction Using Hartley Transform Pre-Coding With Clipping and Filtering Technique in OFDM-NOMA System by : Kalpak Chandekar
Download or read book Hybrid PAPR Reduction Using Hartley Transform Pre-Coding With Clipping and Filtering Technique in OFDM-NOMA System written by Kalpak Chandekar and published by . This book was released on 2020 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Non orthogonal multiple access (NOMA) is one of the fundamental aspects of consideration for the upcoming fifth generation of cellular technology. The working principle of NOMA is based on sharing of the resource block with multiple users so as to have a better spectrum utility. This is different from the previous versions of multiple access techniques used where one resource block was allotted to only one user. Several studies have been made to combine NOMA with OFDM system so that the technical maturity of OFDM system can be used to improve the system performance, called as OFDM-NOMA systems. However, this also introduces a high Peak to Average Power Ratio (PAPR) in the system. This needs to be tackled as a high PAPR decreases the power efficiency of the system. This paper takes in consideration the reduction of PAPR by using a hybrid PAPR reduction using Hartley Transform pre-coding and Clipping and Filtering technique.

Book Synopsis The Novel PAPR Reduction Schemes for O-OFDM-Based Visible Light Communications by : Tian Zhang
Download or read book The Novel PAPR Reduction Schemes for O-OFDM-Based Visible Light Communications written by Tian Zhang and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this chapter, we propose two novel peak-to-average power ratio (PAPR) reduction schemes for the asymmetrically clipped optical orthogonal frequency division multiplexing (ACO-OFDM) scheme used in the visible light communications (VLC) system. In the first scheme, we implement the Toeplitz matrix based Gaussian blur method to reduce the high PAPR of ACO-OFDM at the transmitter and use the orthogonal matching pursuit algorithm to recover the original ACO-OFDM frame at the receiver. Simulation results show that for the 256-subcarrier ACO-OFDM system a ~6 dB improvement in PAPR is achieved compared with the original ACO-OFDM in terms of the complementary cumulative distribution function (CCDF), while maintaining a competitive bit-error rate performance compared with the ideal ACO-OFDM lower bound. In the second scheme, we propose an improved hybrid optical orthogonal frequency division multiplexing (O-OFDM) and pulse-width modulation (PWM) scheme to reduce the PAPR for ACO-OFDM. The bipolar O-OFDM signal without negative clipping is converted into a PWM format where the leading and trailing edges carry the frame synchronization and modulated information, respectively. The simulation and experimental results demonstrate that the proposed OFDM-PWM scheme offers a significant PAPR reduction compared to the ACO-OFDM with an improved bit error rate.

Book excerpt: Communication is one of the important aspects of life. With the advancement in age and its growing demands, there has been rapid growth in the field of communications. Signals, which were initially sent in the analog domain, are being sent more and more in the digital domain these days. For better transmission, even single - carrier waves are being replaced by multi - carriers. Multi - carrier systems like CDMA and OFDM are now - a - days being implemented commonly. In the OFDM system, orthogonally placed sub - carriers are used to carry the data from the transmitter end to the receiver end. Presence of guard band in this system deals with the problem of ISI and noise is minimized by larger number of sub - carriers. But the large Peak - to - Average Power Ratio of these signal have some undesirable effects on the system. In this thesis we have focused on learning the basics of an OFDM System and have undertaken various methods to reduce the PAPR in the system so that this system can be used more commonly and effectively.
