This book presents the effect of dispersion property of optical fiber and multiple access interference (MAI) due to unique signature codes in the optical code division multiple access (OCDMA) systems. A mathematical analysis is presented to evaluate the effect of fiber chromatic dispersion on the bit error rate (BER) performance of a direct sequence optical code division multiple access system with intensity modulation direct detection transmission link using sequence inverse keying optical correlator receiver. MATLAB simulations are used to presents signal-to-noise ratio (SNR) versus...
