Abstract

One of the measures accounting for the decline in the mobile communication is diversity receiving,the implementation of diversity receiving in the direct sequence spread spectrum(DSSS) system is the RAKE receiver.In order to solving the problem about the exorbitant consuming of the correlators,a FPGA design method of improved RAKE receiver about the DSSS signal is presented.Finally,the test results are given.
