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
