P Erformance Analysis of Ds - Cdma Rake Receiver over Awgn Channel for Wireless Communications

In this paper, a software wireless communication simulator performed which simulates a Code division Multiple Access (CDMA) as Wireless cellular telephony has been growing at a faster rate than wired-line telephone networks. This growth has also been fueled by the recent improvements in the capacity of wireless links due to the use of multiple access techniques (which allow many users to share the same channel for transmission) in association with advanced signal processing algorithms. The simulator is a tool to evaluate these design opinions and trades in different scenarios. An efficient method of system is used to speed up the simulations. The simulator can be used to study the performance of a CDMA with variation in system parameters and channel conditions. In this simulator we change the attenuation factor and simulate CDMA with RAKE receiver and without RAKE receiver. Furthermore, we will compare the BER in received data with and without RAKE receiver and also using PIC technique to eliminate further multiple access and multipath interference to improve the performance of the
