Abstract
A systematic approach is proposed for the implementation of multistage linear successive interference cancellation (SIC) in dynamic asynchronous CDMA systems. It is shown that the multistage linear SIC can asymptotically converge to the ideal decorrelating or LMMSE detector in random code time-varying CDMA systems as well as in short-code time-invariant systems. Through simulations it is found that a moderate number of stages gives a performance close to that of an ideal detector
