摘要：
A receiver based on parallel cancellation of multiple access interference (PIC) by bias compensation is considered here for a direct sequence unipolar optical code division multiple access (DS-OCDMA) system. This receiver is dedicated to Multi access Interference (MAI) mitigation. Error on null data occur when a conventional receiver is used. The principle of our proposed receiver consists in reducing the previews output error by amplification of the interfering signals. We also develop the PIC compensated theoretical error probability expression and we show the performance improvement due to this receiver. The performance of such a technique is analyzed in a synchronous network using orthogonal optical codes (OOC) and the results are compared with those for different receivers.
