摘要： 研究了利用MATLAB对非视距(NLOS)和多地型通信环境下的无线宽带802.16/WiMAX的信道仿真。通过建立基于802.16 OFDM PHY的基带模型后仿真，评估NLOS环境下802.16/WiMAX信道在不同调制模式以及两种常用均衡器下的主要性能：宽带无线信道的多路和散射特性(延迟扩展、角度扩展和Doppler扩展)，平均信号干扰脉冲噪声比(SINR)。该研究为后续的系统层计算机仿真和多用户模式计算机仿真提供了良好的理论基础，为FPGA/DSP设计提供了技术参考。

Abstract: The channel simulation of 802.16/WiMAX on NLOS and multi-landform communication environment using MATLAB is studied. By simulating the baseband model based on 802.16 OFDM PHT, it evaluates the major capabilities with different modulate modes and two ordinary equalizers: multichannel and dispersion specialties, SINR, etc.. The study offers theory base for computer simulate in system layer and technical reference for FPGA/DSP design.
