OPTICAL CDMA USING L-PARALLEL CODES.

Fiber optic code-division multiple access (FO-CDMA) has expanded in last decade. This multiplexing scheme uses pseudo-random codes and spread spectrum with a wide frequency range. Every user is provided by specific code words, which subset of optical orthogonal codes (OOC). Here we discuss the Matlab implementation of L-Parallel code scheme to improve the performance of the system. Moreover this paper analyses the performance of FO-CDMA system, multiple access interference and its effect on error probability. Potential applications offered by this technology have been discussed in last.
