摘要

This paper reports on studies of propagation in an urban forested park area to investigate the statistical nature of the time fading for frequencies ranging from 0.9 GHz to 1.8 GHz, as well as to examine the range dependence and the base station height gain. Measurements of the received signal over 30 s intervals for a stationary mobile were used to construct the distribution functions for the fading. In most cases, the distribution could be approximated by a Rician distribution, whose K-factor was found to depend on transmitter height.
