N2 - One extended Welch-Costas (EWC) code family for the wavelength-division- multiplexing/spectral-amplitude coding (WDM/SAC; WS) optical code-division multiple-access (OCDMA) networks is proposed. This system has a superior performance as compared to the previous modified quadratic congruence (MQC) coded OCDMA networks. However, since the performance of such a network is unsatisfactory when the data bit rate is higher, one class of quasi-cyclic low-density parity-check (QC-LDPC) code is adopted to improve that. Simulation results show that the performance of the WS-EWC coded OCDMA network can be greatly improved by using the LDPC codes when data rate is 2.5 Gb/s.
