摘要
Relay technologies have been actively studied and considered in the standardization process of next-generation mobile broadband communication systems such as 3GPP LTE-Advanced, IEEE 802.16j, and IEEE 802.16m. This paper introduces and compares different relay schemes as applied to IEEE 802.16m WiMAX. Simulation results show that relay technologies can effectively improve service coverage and system throughput. Three relay transmission schemes are then summarized and evaluated in terms of transmission efficiency under different radio channel conditions. This paper focuses on the performance analysis of IEEE 802.16m multi-hop relay systems in downlink traffic, MATLAB program was used. Through these tools, a performance analysis of these systems was carried out under different deployment scenarios. Within the different scenarios several aspects of the system design were considered. These include the methods to determine the type of relay mode to maximize the gain that can be provided through the deployment of relays.
