| 摘 要： | 从无线城域网IEEE802.16d协议和OFDM技术出发,首先分析IEEE802.16d协议规定的两种导频结构,并从理论上对这两种导频结构在不同城域网信道模型中的适用性进行研究,然后分别在两种导频结构的辅助下仿真分析相关信道估计方法的性能,最后根据仿真结果为IEEE802.16d系统在不同信道环境下选择适当的导频结构和信道估计方法给出建议。

| Abstract: | Based on Wireless MAN IEEE802.16d standard and OFDM technology, the paper analyses two pilot structures given by the standard and studies the applicability of the structures in Wireless Metropolitan Area Network in theory. Then, the paper evaluates the performance of several channel estimation methods assisted by the two structures in simulation system. Finally, the paper gives some suggestions on the choice of pilot structures and channel estimation methods in different channel environments in the light of the simulation. |
