Abstract

In this paper, we propose a real LTE-A downlink physical layer network with multiple relay stations (RSs). RSs improve the weak received signal at user equipments (UEs). LTE-A with RSs can be used to increase the coverage area of BSs and increase the system capacity. It also enhances the service of the user at cell edge and cover shadowed areas. The performance of the proposed LTE-A network is illustrated and modeled. We also take the effect of different environments scenarios of the WINNER Phase II channel model. The received signals of UEs scenarios are mathematically derived and analyzed in this paper. The weighted least square method for signal combining is mathematically analyzed. The performance of LTE-A with RSs is evaluated by calculating the SER and the capacity for a certain range of SNRs. The SER and capacity are calculated for different UEs scenarios to investigate the effect of RSs in LTE-A network. Simulation results reveal that UEs which receive multiple signals from RSs have low SER values for a certain range of SNRs and enhances the service performance of the UEs at cell edge.
