摘要

提出了一种利用HP网络分析仪测量室内信道传递函数的方法。讨论了系统运行原理，并给出了验证该技术有效性的数据。从频率响应的离散傅立叶反变换(IDFT)中得到复脉冲响应，并对由此产生的影响进行了研究。简要介绍了利用瞬态误差重建分析(TERA)方法进行自回归移动平均(ARMA)建模以避免与数据窗口相关的分辨率损失的结果。结果表明，可以实现60 dB动态范围和5 ns分辨率的脉冲响应。

Frequency measurements of the indoor channel: system evaluation and post processing using IDFT and ARMA modeling

A method for measuring the transfer function of the indoor channel using an HP network analyzer is presented. The theory of system operation is discussed and data confirming the validity of this technique are given. The complex impulse response is obtained from an inverse discrete Fourier transform (IDFT) of the frequency response and the resulting implications are examined. Results from autoregressive moving average (ARMA) modeling using the transient error reconstruction analysis (TERA) method to avoid resolution loss associated with data windows is briefly presented. It is shown that an impulse response with 60 dB dynamic range and 5 ns resolution is realizable.<>
