Parallel Interference Cancellation efficiency for noisy signals in OCDMA system

Abstract : The aim of this paper is to evaluate the robustness of Parallel Interference Cancellation (PIC) to noise contribution for an optical Code Division Multiple Access system. The theoretical expression of thePIC error probability is developed in the case of white additive Gaussian noise. From theoretical analysis, we show that, even with noise contribution, thePIC receiver outperforms the Conventional Correlation Receiver (CCR). Moreover, the results highlight that, for a given performance, thePIC receiver relaxes not only the constraint on the code length, but also the Signal to Noise Ratio compared toCCR. Particularly, this is proofed in access network context, i.e. 30 users withBER lt; 10−9.
