Modeling and Theoretical Analysis of Multistage Interference Cancellation Scheme

Abstract

Previous research developed an asymptotic performance limit (APL) of a multistage parallel interference cancellation (PIC) scheme. However, the derivation was very complex. This study derives a closed form of the APL of a multistage PIC, in which z transformation is used in a new, simple technique to compute the APL. We also derive a closed-form expression of maximum user capacity. The results of the analysis show that this new technique could be used to derive the APL.
