The mathematical formulations are derived for the signal-to-noise ratio and bit-error rate (BER) of SAC-OCDMA system based on the suggested scheme using multi-diagonal (MD) code. Performance analyses are assessed considering the effects of phase-induced intensity noise, as well as shot and thermal noises in photodetectors. The numerical results demonstrated that the proposed scheme exhibits an enhanced BER performance compared to the existing unipolar encoding with direct detection technique. Furthermore, the performance improvement afforded by this scheme is verified using simulation experiments. 2015-04-13T07:03:09Z 2015-04-13T07:03:09Z 2014-03 Article Journal of Modern Optics, vol. 62(5), 2015, pages 327-335 0950-0340 http://www.tandfonline.com/doi/abs/10.1080/09500340.2014.978914#.VStiC9yUeyo http://dspace.unimap.edu.my:80/xmlui/handle/123456789/39433 en Taylor & Francis
