Abstract

In this paper, the relationship between source extinction ratio and performance of optical fast frequency-hop CDMA systems was deeply investigated, and the effect of extinction ratio on BER of systems was analyzed. A new concept of ideal decision, i.e. adjusting decision threshold of receiver according to extinction ratio, was presented. Sensitivity of system performance to extinction ratio degradation and its evaluation was studied. Based on these analyses, the sensitivity of FFH-OCDMA system was compared to that of DS-OCDMA system. Finally, a modified scheme of FFH-OCDMA system was brought forward.
