In this paper, a technique for improving parallel interference cancellation (PIC) receivers with linear estimators is studied in a CDMA system under power control and near-far case. By multiplying the received signal for each user in early stages by a factor superior than unity, the proposed technique significantly reduces the harmful impact of the bias upon BER performance and requires only vector implementation under power control. In order to make the analysis more tractable, the proposed bias mitigation technique is described for a synchronous multi-user communication scenario with binary signalling, non-orthogonal multiple access interference in an additive white Gaussian noise channel.
