摘要:In this paper analysis the performance of a CDMA system by varying the system parameters. CDMA is a popular technology in cellular system due to its superior capacity and performance. In conventional CDMA, obtained better signal to noise ratio by using matched filter because of this rake receiver is used in CDMA to obtain desired signal to noise ratio. Rake receiver is one of the receiver technique, consists of multiple correlators, in which the receive signal is multiplied by time-shifted versions of a locally generated code sequence. To maximize the Signal to Noise Ratio and minimize the Bit Error Rate the CDMA Rake receiver is used. The aim of the paper is to compare the receiver data in CDMA based with and without Rake receiver for different attenuation factor. Results show that, BER performance for WITH Rake and WITHOUT Rake receiver by using GUI and MATLAB.
