摘要

研究了同步多速率DS/CDMA系统的多用户检测问题。我们假设每个用户可能以1 / S的可用数据速率传输。因此，我们设计并评估了一种基于空间交替广义期望最大化(SAGE)算法的新型多用户接收机。有趣的是，结果算法具有可接受的计算复杂度，并且通常优于几个线性多速率接收器。

SAGE-based multiuser detection for multirate DS/CDMA systems

We consider the problem of multiuser detection for synchronous multirate DS/CDMA systems. 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.
