Minimization of outage probability in DS-CDMA system under imperfect successive interference cancellation

This paper studies how to adjust decoding orders to minimize outage probability in DS-CDMA systems with successive interference cancellation (SIC), considering the three real factors, i.e., imperfect SIC, limited received powers of users and existing other cell interference. The method of adjusting decoding orders to minimize outage probability is proposed. Simulation experiments validate our analysis and demonstrate the effectiveness of the proposed method, which can be used in real systems.
