Abstract

In practical environments, CDMA suffers from multiple access interference, inter-symbol interference, and other time-varying effects from the channel. We therefore derive linear complexity multiuser receivers by adaptive algorithms for nonstationary frequency-selective fading channels. A time-varying tapped-delay-line channel model is adopted. The performances of these schemes are shown to be more effective
