Multiuser decorrelating detectors for DS-CDMA on frequency-selective fading channels

Abstract:

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 DSCDMA cases are obtained. The analytic and simulations results have shown that the RDD detector achieves better performance than the MDD detector, with much lower computational complexity. © 2006 IEEE.
