摘要：
In this article two multiuser receivers for DS-CDMA systems on frequency-selective fading channels are analyzed and compared: the rake decorrelating detector (RDD) and the multipath decorrelating detector (MDD). Simple and precise expressions for the bit error probability and for the computational complexity for synchronous and asynchronous DS-CDMA cases are obtained. The analytic and simulations results have shown that the RDD detector achieves better performance than the hIDD -detector, with much lower computational complexity.
