Chirp as Precompensation Factor to Reduce BER on Gaussian and Super Gaussian Pulses in OCDMA System

چکیده
Optical Code Division Multiple Access (OCDMA) is the technique to share a wide bandwidth among a large number of users, OCDMA combines high bandwidth Fiber optic media with flexibility of OCDMA, to provide high-speed connectivity. Multiple Access Interference (MAI) is the main source of performance degradation in OCDMA system .MAI is such a type of interference which caused by multiple cellular users who are using the same frequency allocation at the same time. This is actually a noise which can’t be eliminated anyhow from the system. It can be reduced by decreasing the probability of Bit Error Rate (BER). In this paper we have to examine the way in which the probability of BER would be reduced by considering the chirp effect on Gaussian and Super Gaussian pulses within different conditions.
