Abstract :
Even though there are several interference cancellers that have been implemented, some issues should be considered so that they might be critical parameters in a certain environment. In this paper, we discuss a parallel interference cancellation (PIC) type technique in an asynchronous channel. Subtraction methods are also studied in detail from the viewpoint of bit-by-bit sequential processing for minimization of processing delay. Also we present the pipelined PIC structure (PLPIC) for an efficient implementation of PIC
