Abstract

In this paper, we have proposed two new one-dimensional code families for spectral amplitude coding optical code-division multiple-access (SAC-OCDMA) systems. They are referred as 1) partitioned diagonal code (PDC) and 2) partitioned modified quadratic congruence code (PMQCC). Simulation results show that both of codes can reduce phase-induced intensity noise and support more active users as compared with MQC. Our results show that for similar code length, PDC and PMQCC can support 11% and 14%, respectively, more simultaneous users as compared with MQC. Also, at each synchronous time, the autocorrelations of PDC and PMQCC reach to their peak values and their cross correlations remain one.
