Abstract

The problem of coherent detection for a diversity receiver to combat the severe penalty of transmitting over a Rayleigh fast fading channel is addressed. The principle of per-survivor processing is employed to estimate the channel response for BPSK modulated signals. To achieve this, a symbol aided plus decision directed transmission scheme is used. Simulation results demonstrate that the proposed algorithm can track the fading fluctuations
