Abstract
Recently, a new code structure, zero cross-correlation (ZCC) using anti-diagonal type-identity-column block matrices for spectral amplitude coding-optical code division multiple access (SAC-OCDMA) system, was proposed by K.S. Nisar. The new ZCC code (NZCC) is available for each natural number and has satisfactory code lengths. An effective OCDMA system must have efficient address codes to encode the source with almost zero correlation properties. ZCC eliminates phase-induced intensity noise that consequently improves the bit error rate. In this paper, performance analysis of the NZCC code employing SAC-OCDMA using the direct detection scheme is simulated and compared the efficiency with the other existing codes. The results show that for shorter ranges more number of users accommodated with high data rate by using NZCC code.
