摘要

In WiMAX, various features are introduced to ensure guaranteed QoS for the end users. Along with, these standard features other techniques are also used to further enhance WiMAX capabilities such as use of Relay stations, various types of antennas, modulation and coding schemes to increase throughput and cell coverage. Although, these techniques are very effective but there is still room for further evolution and improvement. The main purpose of IEEE 802.16m WiMAX standard is to improve spectral efficiency, improve VoIP capacity, handover, and speed coverage range. This paper focuses on (ⅰ) the performance analysis of IEEE 802.16m relay-based WiMAX systems in downlink traffic, (ⅱ) the system capacity gain provided, and (ⅲ) a method for optimal RS placement for transparent RSs in IEEE802.16m WiMAX networks, 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. Simulation results show that relay technologies can effectively improve service coverage and capacity of the multi-hop systems, and how various network parameters such as terrain types, reuse factor, sectorization, and RS antenna gain, affect the optimal placement of RSs.
