Abstract :
We propose optical CDMA based on frequency domain encoding enhancement of frequency division multiplexing (FDM/FE-CDMA). Combining both techniques, comprehensive networks with nearly perfect orthogonal transmission can be expected. We analyze the bit error rate (BER) performance of the proposed FDM/FE-CDMA. As a result, we show that the proposed optical CDMA can support a large number of simultaneous user´s compared with the conventional FE-CDMA
