Multiuser Interface Optical Code Division Multiple Access System

CDMA and FIBER OPTICS individually are the best technologies in their respective zones. We all know that CDMA (multiple access technology) is the best as compared to TDMA & FDMA & similar is the case with FIBER OPTICS also. Fiber optic technology is best compare to all other communication technologies. In this Paper, the comparative analysis of a fibre optics CDMA system using Matlab simulation. By varying numerous parameters of the systems, we compare the systems in terms of BER. As the number of active users increases the BER increases.
