Evalution of a RoF system using TSSB based SCM for multiplexing WCDMA based RF channels

Abstract

In the advancing era of technology the need of fast, reliable and affordable data communication links are the threads weaving this huge world wide web. The biggest challenge for communication engineers is to handle a bulky traffic effectively so that the result is low cost communication. Till the second generation evolution of communication system the network was mostly RF based but with the evolution towards 3G the use of optical spectrum was also inherited. But, the after 3G technologies i.e. 4G onwards the communication network has adopted the optical networks along with the existing RF network to deliver fast and economical communication services with the efficient use of RoF (Radio over Fiber) systems. Through this paper we have studied the performance evaluation of as RoF (Radio of Fiber) system if we used WCDMA-RF signals to be sent over an optical fiber using a TSSB SCM technique. The results obtained shows the effects of various types of interferences on ENR (Energy per bit calculated under the effect of total interference to noise ratio) of the dedicated channel for traffic transmission in WCDMA-RoF systems.
