How Temporal Dispersion of Radio Channels Depends on Signal Bandwidth

Abstract

The degree of temporal dispersion of a radio channel is the basis for assessing its transmission capabilities. This paper addresses the practical issue of measuring the temporal parameters of a signal transmitted in the millimeter-wave (38 GHz) range. These parameters provide the basis for assessing the degree of dispersion of the received signal. The measurement results show that both the mean and RMS values of the delay spread depend on the distance between the transmitter and receiver as well as the bandwidth of the transmitted signals. The function description of these relationships (model) is determined based on a statistical analysis of the obtained measurement data obtained in a selected indoor corridor under line-of-sight conditions.
