Frequency domain sounding of MM-wave indoor radio channels

Coherent wide-band frequency-domain measurements of the complex frequency response of mm-wave indoor radio channels are discussed. In addition results of measurements performed in a 2 GHz band centered around 58 GHz in three different rooms at the Eindhoven University of Technology presented. With respect to the considered multipath radio channels it is shown that a 40 dB dynamic range and a 400 ns aliasing-free range are sufficient for a correct estimation of the RMS delay spread from the measurement data.
