Instead of the per-survivor processing (PSP) detector which is the state-of-the-art solution for the joint data channel estimation in fast fading channels, a new reduced complexity maximum likelihood sequence detector (MLSD) based on the particle filtering technique is proposed. It is shown that the particle detector offers a better trade-off between performance and computational complexity, compared to a reduced complexity PSP detector based on the decision-feedback sequence estimation (DFSE) algorithm. Moreover, the computational complexity of this new detector is adapted according to the signal-to-noise ratio.
