Abstract
In this paper, we have proposed two new 1-D code families for spectral amplitude coding optical code-division multiple-access (SAC-OCDMA) systems. They are referred to as (i) partitioned diagonal code (PDC) and (ii) partitioned modified quadratic congruence code (PMQCC). Simulation results show that both of codes can reduce phase-induced intensity noise (PIIN) 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 auto-correlations of PDC and PMQCC reach to their peak values and their cross- correlations remain one.
