Comparison analysis of interference cancellation methods in IDMA system

摘要：

This paper provides a comprehensive study of interference cancellation based on Interleave-Division Multiple-Access system.We first describe the multi-user detection mechanism in the single-path channel to outlining the SIC and PIC methods.Through describing the structures of two methods,characteristics of error correction performance and delay are analyzed.Through combining with two kinds of interference cancellation,parallel SIC is proposed and compared with the traditional approach.By establishing equi-valent channel transfer model,simulation results demonstrate that the proposed scheme can achieve low delay on multi-user communication with less loss of error correction performance.
