With the concept of 3G services OCDMA is one of the important technologies, that provides a very high speed communication. In this paper, multiple users can communicate simultaneously to transfer different kind of data. OCDMA enables the best use of available bandwidth and the spectrum to represent a cost efficient network. But in a network there is always the requirement to increase the security and the efficiency or the throughput of a multiuser communication in the OCDMA network. This paper is about to increase the efficiency in a noisy channel.
