摘要

Multi-hop Relay networks are proposed to fulfill the demanding coverage and capacity requirements for current applications in a cost efficient way. It can be used in IMT-Advanced technologies such as 3GPP LTE-Advanced. In this paper, LTE-A Uplink performance will be improved using Synchronous direct and multi-hop transmission (SDMT) between user equipment and Base Station. Also the effect of adding RS to the network and its position will be discussed. The total LTE-A uplink Throughput, average throughput per user, and Mean File Transfer Time (MFTT) in the LTE-A network are considered as performance measures. This is done and measured as a function of different arrival rates of UEs assigned from random positions in the cell. Adaptive Modulation, and Coding (AMC) scheme with high order 2x4MIMO is used to maximize network throughput with low bit error rate (BER). Simulation results show LTE-A uplink performance improvement using 2x4MIMO-AMC and SDMT scheme with RS at 50% of cell radius towards cell edge.
