| Abstract: | This paper presents a new optical correlator for optical CDMA systems. The bit error probability( BEP) for synchronous and asynchronous optical CDMA systems is also obtained. Numerical results show that systems of synchronous as well as asynchronous with the proposed correlator offers a great improvement in the error pro- bability performance as compared to that with conventional optical correlator. |
