To Study the Effect on Ber by Combining CDMA and TDMA on Optical Communication Link

Ashish Verma, Srashti Vyas

Abstract :

A multiple access scheme referred to as Code-Division Multiple-Access is combined with Time Division Multiple Access to obtain a new hyid multiple access schemes referred to as CDMA-TDMA. This technology implement on electrical domain like mobile communication but it also used for high speed communication like optical fie communication. Optical fie communication (OFC) provides large communication bandwidth, this bandwidth utilized by fast interleaving switch on TDMA technology for simultaneous transmission of large number of multiple users. Optical channel work as dispersive media create an effect of pulse oadening. This system used orthogonal Gold code sequences to provide multiuser environment. The pulse oadening effect generate ISI on channel at the receiver side this also measured by BER. This technology utilizes advantage of both multiple access method, CDMA used for security purpose and TDMA for utilization of bandwidth.
