Analytical Evaluation of Nonlinear Distortion Effects on Multicarrier Signals

<p>Due to their ability to support reliable high quality of service as well as spectral and power efficiency <b> </b>multicarrier modulation systems have found increasing use in modern communications services. However one of the main drawbacks of these systems is their vulnerability to nonlinear distortion effects. <b>Analytical Evaluation of Nonlinear Distortion Effects on Multicarrier Signals</b> details a unified approach to well-known analytical results on memoryless nonlinearities that takes advantage of the Gaussian behavior of multicarrier signals. <p/>Sharing new insights into the behavior of nonlinearly distorted multicarrier signals the book begins with a review of the fundamental principles of multicarrier transmission and multicarrier-based systems. Next it covers well-known results on nonlinear distortion of Gaussian signals and examines the accuracy of the use of Gaussian approximation for evaluating nonlinear effects. It also considers the performance of various multicarrier-based systems in the presence of different types of nonlinear devices.</p><ul> <p> </p> <li>Describes general clipping and filtering techniques to reduce the envelope fluctuations of multicarrier signals</li> <li>Analyzes quantization effects caused by the numerical accuracy required in the DFT computations</li> <li>Discusses quantization requirements of analog-to-digital converters </li> <li>Redefines loading techniques to take into account nonlinear distortion issues on adaptive multicarrier systems</li> <li>Examines the impact of nonlinear signal processing techniques for reducing the envelope fluctuations of OFDMA signals </li> <li>Presents performance results for all the discussed applications</li> </ul><p>The book covers the essential principles of multicarrier modulations including OFDM modulations and other multicarrier schemes.
