Abstract
CDMA interference cancellation engenders biased amplitude estimates of interference, hurting BER. The source of the bias is shown and amplitude estimates are recomputed with downscaled interference estimates. The mean and variance of the new metrics are determined and used to express BER. The optimal scaling factor minimising BER is derived for each interferer
