Abstract

This paper presents a performance analysis of both optical code-division multiple-access (OCDMA) and wavelength division multiplexing (WDM) in an overlay hybrid scheme. Modified quadratic congruence (MQC) code pulses of spectral amplitude coding (SAC) for optical CDMA is utilized as the signature address codes. This hybrid system is described, and its performance is analyzed, taking into account interferences and some types of noises. It is shown that the performance results in terms of both the bit-error rate (BER) and signal-to-noise and interference ratio (SNIR) are accepted in optical communication networks.
