Abstract

This paper introduces an improved multistage parallel interference cancellation (PIC) technique in which the reverse-link synchronous transmission technique (RLSTT) is employed to improve the estimation of data at the initial stage. Because the subtraction of an interfering signal based on an incorrect bit decision quadruples the interference power for that signal, the relatively high decision bit error rate (BER) may lead to a poor cancellation or even a higher BER at the following stages. The RLSTT is a robust approach, which takes into account the fact that the tentative decision at the earlier stages is less reliable than the following stages and lets the earlier cancellation be more reliable. Theoretical analysis demonstrates that a better transmission performance can be achieved by using the RLSTT at the initial stage of PIC.
