Abstract:

LTE-Advanced is a communication standard for cellular networks. It uses the physical layer uplink transmission technology based on single carrier frequency division multiple access (SC-FDMA) and down link based on orthogonal frequency division multiple access (OFDMA). The system is designed using OFDMA in both uplink and downlink with deployment of amplify and forward relays. To reduce the effect of noise, equalization has been applied on the receiver side. In order to improve the system throughput power allocation scheme has been added. Maximum achievable rate and throughput are obtained after performing ZF equalization and power allocation.
