Taschenbuch. Condición: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - The aim of this book is to present a theoretical development of higher order statistics (HOS) and their applications in blind identification and equalization domain. We provide a description of HOS theory, then we introduce the application of HOS to identify the transmission channels. In the one hand, we present a theoretical development linking cumulants and impulse response channels. In the other hand, these relationships are used to develop several algorithms. Finally, to assess the performance of these approaches to identify the parameters of communications channels, we consider theoretical channel models. One ends with simulation results illustrating the performance of the proposed methods. In the part of the implementation of HOS in blind equalization problem, we have checked the effectiveness of the proposed algorithm on a Multi-Carrier Code Division Multiple Access (MC-CDMA), for this we have chosen fast fading channels called BRAN. In this context, we use the equalizers techniques after channel identification to correct channel distortion. Theoretical analysis and numerical simulation results in noisy environment show that the proposed algorithm reduces the bit error rate. …

Blindequalization is a digital signal processing technique in which thetransmitted signal is inferred (equalized) from the received signalwhile making use only of the transmitted signal statistics. Hence, theuse of the word blind in the name. Blind equalization is essentiallyblind deconvolution applied to digital communications. Nonetheless, theemphasis in blind equalization is on online estimation of the equalizerfilter, which is the inverse of the channel impulse response, ratherthan the estimation of the channel impulse response itself. This is dueto blind deconvolution common mode of usage in digital communicationssystems, as a mean to extract the continuously transmitted signal fromthe received signal, with the channel impulse response being ofsecondary intrinsic importance. The estimated equalizer is thenconvolved with the received signal to yield an estimation of thetransmitted signal.…
