This book was released on 2015-09-22 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: MIMO-OFDM transmission systems provide a high spectral efficiency, robustness in the frequency selective channels and flexibility in the resource allocation. However, like a single-input single output (SISO) OFDM systems, similarly MIMO-OFDM has one main drawback i.e. high sensitivity to the nonlinearities in RF front-ends due to the large envelope fluctuation of OFDM-based signals. When a nonlinear high power amplifier (HPA) is used, large back-off is necessary to avoid strong nonlinear distortion causing performance degradation. On the other hand, when the HPA is operating in the linear region, the power efficiency is low. To avoid nonlinear distortion transmitter-side or receiver-side solution can be employed with advantage. Here, a transmitter-side method based on using the tone reservation technique is proposed for the space-frequency block coded (SFBC) OFDM systems with three and more transmit antennas. Then, new receiver-side iterative method for the detection of nonlinearly distorted symbols received by the receiver of SFBC-OFDM transmission system is designed.

Download or read book Techniques for Nonlinear Distortion Suppression in Radio Over Fiber Communication Systems written by Biagio Masella and published by . This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radio over fiber (RoF) is a promising technology that will indisputably compete as a viable solution for future wireless, cellular and broadband networks. RoF, when combined with dense wavelength division multiplexing (DWDM), such as SONET/SDH, it can become a complete flexible and cost effective solution to the global telecommunication network, where asynchronous and synchronous communications may be efficiently supported. Subcarrier modulation (SCM) is utilized to modulate a RF signal on light, which in turn will be transmitted by fiber. Unfortunately, the transmission in most cases may become corrupted by nonlinear distortion that is induced by the nonlinear response of the optical transmitter, optical receiver and chromatic dispersion of the single mode fiber (SMF). The nonlinear distortion degrades the receiver sensitivity, which leads to a poor bit error rate (BER) and spurious free dynamic range (SFDR). Ultimately, this will increase RoF system costs and render it impractical. The objective of this thesis is to develop linearization methods that reduce the nonlinear distortion, increase receiver sensitivity and increase SFDR. The designs should also address the entire RoF system by combating the optical power fading issue that will be discussed in Chapter 2 without significantly adding great expense and complexity to the RoF system. Four optical linearization methods are proposed and shown through extensive simulation and/or experimentation to outperform similar existing linearization systems described in literature. The proposed single wavelength balanced system is shown to improve the suppression of 2nd order distortion over the dual wavelength balanced system, thereby leading to greater improvement in receiver sensitivity and BER. Furthermore, the design also suppresses relative intensity noise (RIN). The proposed tunable fiber Bragg grating (FBG) balanced system is capable of suppressing both 2 nd and 3 rd order distortions despite which RF carrier that is used. Furthermore, it was shown to outperform the conventional RoF system in terms of receiver sensitivity and BER. The proposed asymmetric Mach-Zehnder modulator (MZM) has been shown to generate optical single sideband (OSSB) transmissions and outperform the dual-parallel modulator, by improving 3rd order intermodulation distortion (3IMD) suppression and increasing SFDR. The final proposed linearization method is the mixed-polarization MZM, where OSSB is also generated and outperforms the conventional OSSB RoF system in terms of 3IMD suppression and SFDR. Furthermore, close form expressions for SFDR are developed for the final two designs, which is crucial in study of their stability and performance.

This book was released on 2019-11-23 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a synthesis of the research carried out in the Laboratory of Signal Processing and Communications (LaPSyC), CONICET, Universidad Nacional del Sur, Argentina, since 2003. It presents models and techniques widely used by the signal processing community, focusing on low-complexity methodologies that are scalable to different applications. It also highlights measures of the performance and impact of each compensation technique. The book is divided into three parts: 1) basic models 2) compensation techniques and 3) applications in advanced technologies. The first part addresses basic architectures of transceivers, their component blocks and modulation techniques. It also describes the performance to be taken into account, regardless of the distortions that need to be compensated. In the second part, several schemes of compensation and/or reduction of imperfections are explored, including linearization of power amplifiers, compensation of the characteristics of analog-to- digital converters and CFO compensation for OFDM modulation. The third and last part demonstrates the use of some of these techniques in modern wireless-communication systems, such as full-duplex transmission, massive MIMO schemes and Internet of Things applications.
