Abstract :
In order to gain insights on equalization design in wireless mobile communication systems, we compare the performance of several multi-channel MLSE equalizers which adaptively track fast-fading channels. Commonly-used channel tracking schemes, decision-directed recursive least square (DD/RLS), per-survivor processing recursive least square (PSP/RLS) and other reduced-complexity MLSE algorithms are considered. Simulation results that illustrate the performance of the equalizers working with various channel tracking schemes are presented
