A theoretical analysis is presented to evaluate the impact of fiber chromatic dispersion on the bit error rate performance of a direct sequence optical code division multiple access (DS-OCDMA) system with intensity modulation and direct detection (IM/DD) transmission link using sequence inversion keyed (SIK) optical correlator. Computed results are(More)
In this paper we study and analyze Bit Error Rate (BER) performance for optical communication system using Differential Phase Shift Keying (DPSK) modulation scheme. Specifically, after developing an approximate form BER expression, we study the BER performance for different system parameters such as fiber length, gain and number of amplifier. With the aid(More)
