Simulation of MQC code for optical CDMA PON system
In this article, a network structure of passive optical network (PON) in conjunction with optical code division multiple access (OCDMA) technique is theoretically investigated using Modified Quadratic Congruence (MQC) codes as a signature sequence, and taking into account the effects of various noises such as shot noise, phase-induced intensity noise (PIIN), thermal noises and multiple access interference (MAI) noises. The system also has been simulated with 9 users simultaneously over a 20km channel length, utilizing spectral amplitude coding (SAC) detection scheme with fiber Bragg grating filters. The results show that, the system based on SAC scheme and MQC codes at 622Mb/s, was achieved the error free transmission (bit error rate BER <;10-9) for a fully loaded PON. Hence, the system shows good performances when various system parameters applied such as the optimum transmit power, channel length are varied.
