Abstract

Complexity and detection delay are major issues for applying interference cancellation to practical CDMA systems. We introduce a new interference cancellation approach for multiuser detection. This detector combines both parallel interference cancellation (PIC) and successive interference cancellation (SIC) techniques. It has a short detection delay as in PIC and low computation complexity as in SIC
