In this paper, to increase normalized throughput of the optical wireless code-division multiple-access (CDMA) system, modified pseudo orthogonal M-sequences (MPOMS) are considered as optical pseudo-noise (PN) code. Moreover, the bit error rate (BER) performance of the optical wireless CDMA system using multi-pulse pulse position modulation (MPPM) is also derived in the presence of the scintillation,...
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...
