Bentrcia, A. and Sheikh, A.U. and Zerguine, A. (2004) Successive interference cancellation using stage dependent decision functions. TENCON 2004. 2004 IEEE Region 10 Conference, B.
In this paper, we introduce the concept of stage-dependent decision functions. The latter exploit the improvement of the soft-decisions' reliability with increasing number of stages to take more hard-decisions and thus cancels more noise from stage to stage. We prove that if the stage-dependent thresholds can be optimized at each stage then the nonlinear SIC can approach the single user bound. Simulation results show significant BER improvement compared to the SIC using stage-independent decision functions.
