Performance analysis of MPC in synchronous OCDMA system

Abstract

Prime codes are a family of optical address codes that are suitable for optical fiber code division multiple access (OCDMA) systems using all-optical processing. Incoherent optical signal processing is used for generation of prime codes (PC) and modified prime codes (MPC). Prime codes are developed for an optical fiber network using (asynchronous) code division multiple access (CDMA). Prime codes are then modified to fit a synchronous transmission format which can accommodate a larger number of subscribers and more simultaneous users than CDMA. Bit error rate (BER) performance comparison of CDMA and synchronous code division multiple access (S/CDMA) have been made using Gaussian approximation technique.
