摘　　要：随着无线通信技术的发展,现有的WiMAX系统由于存在着覆盖有盲区和系统容量不足等问题,不能很好满足新一代无线通信系统更高传输速率、更好信号覆盖和更好移动性的要求,需要一种新的部署方法来解决。在对无线中继技术进行相关分析的基础上,提出基于IEEE802.16j的宽带接入参考模型和协议栈,并进行中继多跳接入和单跳接入掉话率的仿真比较,结果表明中继接入可以在降低系统成本的同时有效提升系统的性能。With the development of wireless communication technology,the WiMAX system,for its blind spots of coverage and insufficient system capacity,is hardly to satisfy the demand of new-generation wireless communication system with higher transmission speed,better signal coverage and mobility.A new deployment method is needed to solve this problem.Through correlation analysis on the wireless relaying technology,this thesis proposes a broadband access reference model based on IEEE802.16j,including protocol stack.Simulation and comparison of dropping rate between relaying multi-hop access and single-hop access indicate that the relaying access could reduce the system costs while improve the system performance.
