Design and Analysis of DS-CDMA RAKE Receiver Simulator for Wireless Communication

This paper develops a software wireless communication simulator which simulates a Code Division Multiple Access (CDMA). CDMA is a popular technology in cellular systems due to its superior capacity and performance. The simulator is a tool to evaluate these design options and trades in deferent scenarios. The backbone of this system is a wireless CDMA single user link built using Matlab. An efficient method of system modeling is used to speed up the simulations. This simulator can be used to study the performance of a CDMA wireless link with variation in system parameters and channel conditions. In this simulator we can change the attenuation factor and simulate CDMA with RAKE receiver and without RAKE receiver, the transmitted data and received data is show in form of graph, we can compare the received data with and without RAKE receiver for different attenuation factor.
