A linear front end for iterative soft interference cancellation and decoding in coded CDMA
Alberto Tarable, G. Montorsi, Sergio Benedetto · 2002
A new suboptimal turbo receiver for coded CDMA is presented. The user-separating front-end of this receiver has been thought of as the extension of linear multiuser detectors to an iterative structure. The complexity of this receiver is shown to be O(K), where K is the number of users. Simulations show that, for sufficiently high signal-to-noise ratios, the linear-US receiver tends to single-user performance.
