ABSTRACT

Efficient resource allocation is the major issue in the development of fourth generation mobile communication systems. A very high data rate is needed for advanced multimedia applications and internet. 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 of correlated Rayleigh fading processes is used. Simulation results shows that for downlink transmission a
very high data rate ,upto hundreds of Mbps can be obtained using improved algorithm under the constraints 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 with ACA algorithm and shows significant improvement in the throughput for the three combining schemes.
