BER Analysis of Incoherent SAC-OCDMA System Using ZVCC in a Noisy Environment

In this paper the performance of Incoherent SAC OCDMA system has been evaluated in a noisy environment using ZVCC (Zero Vector Combinatorial Code set). CDMA system allows multiple users to access the channel simultaneously but is limited by some problems like MAI (multiple access interference), PIIN (Phase induced intensity noise), thermal noise, and shot noise still exists in this system. It is observed from the results that as effective power is increased, the intensity noise becomes the main factor of performance degradation of the system.
