摘　　要：根据信道脉冲响应波形,文章对井下UHF宽带无线电波多径信道进行了频域自回归(AR)建模与仿真,证明了频域AR模型在井下多径信道应用的可行性,这为井下宽带乃至超宽带无线通信的信道模型计算机仿真研究提供了一种新思路。仿真结果表明,频域AR模型只需要很少的模型参数就可给出一个比较精确的信道描述,是信道建模比较理想的选择。According to impulse response waveform of radio channel, the paper made modeling and simulation of frequency domain autoregressive （AR） for UHF wideband radio multi-path channel of coal mine underground, and proved feasibility of AR model applied in the multi-path channel of coal mine underground, which gave a new idea for computer simulation research on the channel model of wldeband as well as ultra-wideband wireless communication of coal mine underground. Simulation result showed that the frequency domain AR model only requires a small quantity of parameters to gain a relative accurate channel description, which is an ideal choice for channel modeling.
