Abstract: For the UWB indoor multi-path channel,because of clustering property of signal propagation,the modified Saleh-Valenzuela model which needs more parameters is usually adopted,however,the frequency domain AR model which possesses special features has been pay great attention to in recent years.In this paper the method how to apply the pole/zero pattern to the frequency domain AR modeling is discussed and the simulation results are gained combining with an example.The results show that the frequency domain AR model only requires less number of parameters to gain a more accurate model description,it is an ideal choice for UWB channel modeling.

Key words: ultra-wide band, frequency domain autoregressive model, multi-path channel, pole/zero pattern, modeling and simulation
