Abstract :
In this paper, we introduce the optimization of bit error rate (BER) in parallel cancellation of multiple access interference (PIC) using the bias compensation with a direct sequence unipolar optical code division multiple access (DS-OCDMA) system. This receiver is dedicated to mitigate Multi access Interference (MAI). The principle of our proposed receiver consists in reducing the output error by amplification of the interfering signals. We develop the PIC compensated theoretical error probability expression. The performance of such a technique is analyzed in a synchronous network using orthogonal optical codes (OOCs) and the results are compared with those for different receivers.
