Summary:
In this paper, to increase normalized throughput of the optical code-division multiple-access (CDMA) system, optical-CDMA systems with multi-pulse pulse position modulation (MPPM) using the modified pseudo orthogonal M-sequence sets is proposed. The throughput performance and bit error rate (BER) are evaluated by theoretical analysis. Consequently, the normalized throughput of the proposed system can achieve 1.35 [bit/chip] when the number of slots per frame is 16. Furthermore, BER of the proposed system is superior to that of the conventional systems.
