Study of Temporal En/Decoder Effect on OCDMA Steganography System´s Performance

Optical code division multiple access (OCDMA) en/decoder is the key factor affecting the performance of optical steganography transmission system. In this paper, the performance of optical steganography transmission system is investigated with different chip length of the superstructured fiber Bragg grating (SSFBG) en/decoders. The performance of the steganography system between pulse width of the steganography signal and chip length of the en/decoder are obtained. From the analysis of simulation result, we can see when chip length of the en/decoder and pulse width of the steganography signal meet some condition, resulting in a better system performance.
