Abstract

We study a novel single-user receiver for the forward link of a B-CDMATM system in multipath fading environments. For a typical forward link all B-CDMATM signals transmitted from a base-station arrive at a given mobile receiver through identical multipath fading channels. This renders the conventional matched filter RAKE receiver decidedly sub-optimum. The proposed receiver consists of a bank of digital correlators (BDC) followed by a linear combiner. It treats multiple access interference (MAI) as additional background noise, while taking into account in an optimal way the homogeneous characteristics of the MAI. Numerical results are provided showing that the proposed receiver leads to significant system performance enhancement relative to the matched filter RAKE receiver and zero-forcing (ZF) channel equalizer (inverse filter receiver).
