Prime Code efficiency in DS-OCDMA Systems using Parallel Interference Cancellation

Abstract : In this paper, we are studying the Prime Codes (PC) efficiency, in direct Sequence Optical Code Division Multiple Access system (DS-OCDMA) using Parallel Interference Cancellation receiver (PIC). We develop the analytical expression of the error probability upper bound in the chip synchronous case, for PC. The main result of our work is that the PIC receiver totally suppresses the effect of Multiple Access Interference (MAI) for Prime Codes, and leads to an error free O-CDMA link in the noiseless case, for whichever employed PC. Simulation results are presented to validate the theoretical analysis. We also show that the PIC receiver permits reducing the required code length for a given Bit Error Rate compared to the Conventional Correlation Receiver. Finally, we compare the PC to the Optical Orthogonal Codes (OOC), and show that the use of PC allows a significant reduction of the required SNR.
