Abstract

Successive interference cancellation (SIC) is a well known technique to improve the bit-error rate of multiuser detectors. Since an incorrectly detected and cancelled symbol doubles the interference caused by the corresponding user, the performance gain is highly dependent on the cancellation order of the users. A popular approach is to order the detection and cancellation based on the received energy of each user, or more sophisticatedly, the average error probability. However, this is not necessarily optimal. In this paper, new ordering methods, based on the instantaneous error probabilities within each symbol period are proposed, to improve the performance of successive cancellation detectors.
