摘要：

Propagation measurements were performed in an urban area at 8.45 GHz. We examined the delay and angle spread characteristic of the main arrival wave at the base-station receiving antenna. The delay spread (sigma (d)) tends to increase with the angle spread (sigma (main phi)). Both sigma (main phi) and sigma (d) in the line-of-sight (LOS) environments were smaller than those in the non-LOS (NLOS) environments. sigma (d) in the NLOS environments was greater than that at locations with the same angle spread in the LOS environments. sigma (main phi) in the LOS environments did not depend on the distance between the transmitter and receiver, Likewise, in the NLOS environments, it did not depend on the distance between the corner and receiver.
