We study the effect of cancellation order on bit error rate (BER) performance of a code division multiple access (CDMA) system employing a linear successive interference cancellation (SIC) receiver in both an additive white Gaussian noise (AWGN) channel and a Rayleigh fading channel. Four different ordering schemes are studied. We show that changing the cancellation order can lead to a significant change in the BER performance.
