Abstract :
A novel method using concatenated code to pre-encode is proposed to reduce the impact of any system impairment and multiple access interference (MAI) in optical code division multiple access (OCDMA) system. The bit error rate (BER) performance is derived taking into some noise and the MAI. From both theoretical analysis and numerical results, we can be able to show that the proposed system has good performance at a BER of 10-9 with a gain of 6.4 dB improvement achieved using the concatenated code as the pre-code
