Abstract
This paper illustrates the use of "averaging" to improve the convergence rate of adaptive sign regressor and sign error multiuser detectors. The ingenious concept of averaging was invented by Polyak (1990) - this paper analyses the performance of averaging in the sign error and sign regressor adaptive blind multiuser detection algorithms in DS/CDMA systems
