Intersymbol Decorrelating Detector for Asynchronous CDMA Networks with Multipath
EURASIP Journal on Wireless Communications and Networking, 2005 Most reported multiuser detection techniques for CDMA systems need the channel estimation including the delay spread and the parameters of the multipath channel of the desired user. This paper proposes an intersymbol decorrelating detector that makes use
