Abstract :
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.
