Abstract :
In this paper, we study the performance of the multiuser detection in a direct sequence optical code division multiple access (DS-OCDMA) system using novel periodic optical encoder applied to fiberto-the-X (FTTX) passive optical network (PONs). The performance of our system is analyzed in a synchronous network using multilevel periodic codes (ML-PC) with a conventional receiver model and the results are compared with those for different receivers. Two solutions to improve the performance are proposed: the parallel interference cancellation receiver (PIC) and the successive interference cancellation receiver (SIC) simulated in the ideal case.
