Abstract

With the demand for high capacity (multimedia) services, wideband CDMA (WCDMA) has become an attractive multiple access scheme for 3rd generation wireless systems. Coming with higher data rate, the application of WCDMA brings with it new challenges in terms of multiple access interference (MAI) and intersymbol interference (ISI) suppression due to the fact that compared to the `regular' CDMA, the delay spread is no longer only a few chips. Most of the literature on multiuser detection so far focused on algorithms which, due to high computational/hardware complexity, are unsuitable for large delay spread channels. In this paper, we present an adaptive symbol-based signal separator based on multishot matched filtering which is suitable for the asynchronous large delay spread fading channels characteristics.
