Pulsed laser source coherence time impairments in a direct detection DS-OCDMA system

We investigate the impact of laser source coherence time on bit error rate (BER) and autocorrelation function performances of a direct sequence OCDMA system. Congruence codes are suggested to reduce the observed coherence effects.
