English Abstract

The problem of detection of signals in fast multipath fading channels is increasingly gaining more attention, to achieve better performances, faster and more reliable communications, at the receivers. In this thesis, a new FSK receiver structure, which is dubbed the Multisampler receiver, is proposed to work in fast multipath fading channels. Contrary to the other conventional FSK receivers, this receiver samples the received signals of nonresolvable fast multipath fading channels at a distinct sampling rate in each of its branches. The sampling rate of a certain branch, is a four-fold of one of the transmitted frequencies in the transmitted frequency set. The received frequency is then estimated using a parameteric estimator, in each branch. The error in frequency estimation is calculated. The magnitudes of estimation errors of all the branches are compared to each other, and the branch with the lowest error magnitude is decided in favor of. The multisampler receiver is compared to other conventional receivers, to determine its performance. The multisampler receiver is found to give the best results for the realistic cases of fast multipath fading channels.
