Abstract

In this paper, to achieve high maximum throughput performance, the optimum combination of the optical PN code and modulation scheme is presented. Moreover, bit error rate (BER) performances of the wireless OCDMA system using chip-level detection are evaluated from the theoretical analysis in the multi-user case. Consequently, in the wireless OCDMA system with the chip-level detection, the maximum throughput performance of the multi-pulse PPM (MPPM) systems with the optical pseudo noise code generated by M-sequence is better than that of the MPPM systems with optical orthogonal code and that of the MPPM system with extended prime code sequence.
