  In an urban environment, a multipath propagation is one of the basic
phenomena affecting a quality of received signals. This causes dispersions in
time and angular domains. Basic parameters describing these dispersions are the
rms delay spread and rms angle spread, respectively. The delay spread is
related to a frequency of the transmitted signal and the nature of the
propagation environment. In this paper, we show a mutual relationship between
the time and angular dispersions in the received signal. The obtained
simulation results present a comparison of the described dispersions for two
different frequencies. In this case, the multi-elliptical propagation model and
standard model developed by 3GPP are the basis for the simulation analysis of
new communication system solutions.
