摘要
本文提出了一种新的用于光码分多址系统的光相关器,并对光同步和异步系统给出了误比特率公式。数值仿真结果表明,无论是异步还是同步系统,这种光相关器的误比特率性能都优于传统光相关器的性能。
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.
