Abstract
To get a better bit error rate (BER) performance of the optical code division multiple access (OCDMA) systems, an OCDMA scheme using 3rd order Chebyshev chaotic sequence is proposed based on the study of the principle of phase shifted superstructure fiber Bragg grating encoder/decoder. The code selecting method using simulated annealing algorithm is investigated. Simulations indicate that the BER performance of the system with chaotic sequences is better than that with Gold sequences, and the proposed code selecting method is effective.
