Abstract :

Rayleigh�s distribution is mainly used when fading wireless medium does not have proper line of sight (LOS) path and is dominated by a large number of non-line of sight (NLOS) paths due to reflections of the received signal. Also because of relative motion of the base station and mobile station, a random frequency shift is generally introduced in the carrier, which can be realized in terms of Doppler spread. In case of Rayleigh�s fading channels, generally two critical problems arise in receiver design those are accurate estimations of channel coefficients followed by mitigation of channel impairments like inter symbol interference (ISI) and fading in presence of user mobility. The accuracy of estimated channel state information (CSI) is really crucial to design robust equalizer for reconstruction of bit sequence and the equalizer performance is affected by the fading rate and Doppler spread. The main research is oriented towards the exploitation of underlying sparseness of block adaptive filters through L0-norm penalty for accurate estimation with stable convergence which helps to design computationally efficient adaptive models that can be effectively used for practical applications. Block and fast block processing can be quite effective techniques for outdoor fading wireless environment with proper choice of modulation formats.
