Frequency Domain AR Modeling of Multi-path Channel of Underground UHF Wideband Radio Propagatio

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 wideband 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.
