Abstract :
Space-time processing is often used to eliminate intersymbol interference (ISI) and multiple access interference (MAI) which are main sources of transmission errors in communication systems. This paper carries out an analysis of applicability of the decision feedback equalizer (DFE) for multi-user detection in multiple antennas commercial TDMA standards: IS-136 and GSM/EDGE. The principal feature of the studied algorithm is a feedback connection among all detected users. The algorithm is implemented using indirect reduced-order adaptation and bootstrap processing. Its advantages and drawbacks are shown through simulations.
