Abstract:
In this paper, we introduce the optimization of Bit Error Rate (BER) in parallel cancellation of multiple access interference (PIC) using a novel periodic optical encoder applied to fiber-to-the-X (FTTX) passive optical network (PONs) with a direct sequence optical code division multiple access (DS-OCDMA) system. The principle of this structure of receiver consists to reduce the output error in the data received. The performance of our system is analyzed in a synchronous network using multilevel periodic codes (ML-PC) and the results are compared with those for different receivers.
