Efficient resource allocation is the major issue in the development of fourth generation mobilecommunication systems. A very high data rate is needed for advanced multimedia applications andinternet. This paper evaluates the performance of improved algorithm for the future Long Term Evolution(LTE) advanced standards-the 3GPP candidate for 4G. For the analysis autoregressive model ofcorrelated Rayleigh fading processes is used. Simulation results shows that for downlink transmission avery high data rate ,upto hundreds of Mbps can be obtained using improved algorithm under theconstraints of available transmit power and given BER. Same algorithm is also analysed by varying the no.of users and spreading factor. Performance of the improved algorithm is evaluated in comparison withACA algorithm and shows significant improvement in the throughput for the three combining schemes
