摘要：
In this paper we consider the problem of multiuser detection for synchronous multirate DS/CDMA systems. To this end we assume that each user may transmit at one out of S available data-rates. Thus, we devise and assess a novel multiuser receiver based on the Space Alternating Generalized Expectation maximization (SAGE) algorithm. Interestingly the,resulting algorithm has an acceptable computational complexity and; in general outperforms several linear multirate receivers.
