Abstract
This paper deals with a multiuser detector based on a new decorrelating approach for asynchronous up‐link DS/CDMA communications in which the QPSK modulation scheme is used in transmission. It is shown here that the receiver proposed is near–far resistant and exhibits a low complexity which allows real‐time operation. Performance is expressed in terms of bit error rate (BER) which has been derived by simulations under the assumption of a slowly frequency‐selective Rayleigh fading channel.
