Abstract:The model of received signal in CDMA systems is given in this article Based on the analysis of time processing and conventional Rake receiver, we discuss the concept and principle of 2-D Rake receiver, which is the combination of smart antenna and Rake receiver The output SNR of two kinds of receivers are also compared and the result indicates that the capacity and performance of 2-D Rake receiver exploiting integrated space time processing technique will be improved significantly in CDMA systems
Keywords:code division multiple access  smart antenna  space time processing  Rake receiver
