摘要
Parallel multistage interference cancellation is a promising approach for practical implementation of multiuser detection. However, as this paper shows, direct implementation of multistage parallel interference cancellation (i.e. complete cancellation of the estimated interference) results in biased estimates and consequently reduced performance. A simple technique that mitigates the effect of the bias and provides significant performance gains over the direct implementation is presented.
