Wideband characterisation of fading mobile radio channels
John David Parsons, A.S. Bajwa · IEE Proceedings F Communications Radar and Signal Processing · 1982
A description of the physical mechanism causing multipath propagation in built-up areas is followed by a discussion of the various ways in which fading radio communiction channels can be described. It is shown that characterisation in the time-delay/Doppler-shift domain explicitly illustrates the multipath nature of the channel and provides parameters relevant to system design. A brief discussion of channel-sounding techniques is followed by a description of a wideband channel sounder using matched-filter signal processing in the receiver.
