Self-Consistent Signal-to-Noise Analysis of CDMA Multiuser Detection withM-Ary Phase-Shift Keying

Abstract

We present a theory of the performance of parallel interference cancellation (PIC) for code division multiple access (CDMA) multiuser detection with \(M\)-ary phase-shift keying (\(M\)-ary PSK) in the large-system limit. The behavior of PIC is essentially the same as that of the associative memory model. Therefore, we analyze the PIC for CDMA using self-consistent signal-to-noise analysis (SCSNA), which was developed to describe the behavior of the associative memory model. We obtain a quantitative description of the performance of PIC.
