Abstract :
Error correction codes can be used to significantly improve the bandwidth efficiency of all-optical asynchronous prime-code CDMA networks. It is shown that using asymmetric error correction (AEC) codes not only greatly improves the bit error rate performance of optical CDMA systems, but also can efficiently increase the number of active users without increasing the complexity of tunable optical CDMA encoders/decoders. Therefore, the use of AEC codes can dramatically reduce the network cost
