Nonlinear Successive Interference Cancellation for Turbo-CDMA

摘要

This article presents a novel iterative technique for joint detection and decoding of Direct Sequence-Code Division Multiple Access (DS-CDMA) systems. A turbo-CDMA successive interference cancellation structure is proposed with complexity in O(K), where K is the number of users. The structure can be implemented easily and converges rapidly to the single user bound.
