Performance Analysis of a Multiport Encoder/Decoder in OCDMA Scenario

We investigate the use of a single multiport encoder/decoder in an optical code-division multiple access network scenario. We present a comparison between the performance of two sets of phase-shifted keying codes, and evaluate the bit error rate and the spreading effect due to the asynchronous access. We also investigate the performance degradation due to the presence of both multiple access interference and beat noises.
