Download or read book Novel Adaptive Signal Processing Algorithms for Wireless Communications written by Shannon David Blunt and published by . This book was released on 2002 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this research we propose two novel adaptive signal processing techniques to enhance the quality of a received signal that is transmitted over a wireless communication link. In the first we develop a family of efficient echo cancellation algorithms that require no knowledge of the echo-path. Echoes significantly degrade the quality of service in wireless communications because of extra delay introduced into the transmission path from the speech compression/decompression process. To remove these echoes we must identify the echo-path impulse response that in general is sparse (predominantly zero). This makes it desirable to adapt only those filter coefficients corresponding to the non-zero regions of the impulse response. To accomplish this we exploit the hierarchical structure and temporal localization property of the wavelet decomposition. In this way we are able to adapt a small subset of filter coefficients and then, based on the coefficients that are significantly different from zero, to accurately identify the remaining coefficients that require adaptation as well. This approach was previously applied to the case of the Haar transform. The current work generalizes it to the wavelet decomposition in which any orthogonal or bi-orthogonal wavelet can be used. Due to the ability of longer wavelets to achieve greater input decorrelation, the resulting algorithm is capable of a significant improvement in convergence speed and computational complexity over LMS. The other novel adaptive technique we propose is in the physical layer to reduce the effect of multiple-access interference (MAI) for direct-sequence code-division multiple-access (DS-CDMA) wireless communication systems. A DS-CDMA system allows many users to share the same spectrum and distinguishes different user's data through the use of signature codes. In practice, these signature codes are not orthogonal and therefore data from different users interfere with each other and creates MAI. Past approaches have either used classical estimation techniques where each unknown user symbol to be estimated is treated as a deterministic parameter, or Bayesian techniques that treat each unknown user symbol as a stochastic parameter but restrict it to a finite set of discrete possible values. In this research, we employ Bayesian estimation such that each user symbol is treated as a stochastic parameter with continuous Gaussian distributions centered at the true symbol values of the data constellation. This allows us to develop a gradient-based maximum a posteriori (MAP) estimator that takes the structure of the particular symbol constellation into account in order to dramatically improve symbol estimation accuracy.

Emphasisthroughout the book is on joint optimization across differentlayers of a communications system based on an integrated approach.Examples of popular wireless systems, such as TDMA, wideband CDMA(UMTS), and HSDPA, are used throughout as practical illustrations.Each chapter ends with a summary that reviews key points and a setof problems that lets readers test their knowledge and continue todevelop their skills as they progress to new topics. Figures andtables are also used extensively to help readers visualize complextheory and systems. Combining theory, design, and application into one integratedapproach, this is a superior reference for advanced communicationstheory courses.

This book was released on 2007-10-25 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optimization of adaptive signal processing algorithms for wireless communications is based on a model of the underlying propagation channel. In practice, this model is never known perfectly. For example, its parameters have to be estimated and are only known with significant errors. In this book, a systematic treatment of this practical design problem is provided.

Download or read book Adaptive and Iterative Signal Processing in Communications written by Jinho Choi and published by Cambridge University Press. This book was released on 2006-11-16 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adaptive signal processing (ASP) and iterative signal processing (ISP) are important techniques in improving receiver performance in communication systems. Using examples from practical transceiver designs, this 2006 book describes the fundamental theory and practical aspects of both methods, providing a link between the two where possible. The first two parts of the book deal with ASP and ISP respectively, each in the context of receiver design over intersymbol interference (ISI) channels. In the third part, the applications of ASP and ISP to receiver design in other interference-limited channels, including CDMA and MIMO, are considered; the author attempts to illustrate how the two techniques can be used to solve problems in channels that have inherent uncertainty. Containing illustrations and worked examples, this book is suitable for graduate students and researchers in electrical engineering, as well as practitioners in the telecommunications industry.
