It is important to study the propagation characteristics for mobile communication systems using street microcells in order to establish technology that enables high-speed communications. Delay spread characteristics in a street microcell environment depend on both the transmitting and the receiving points of communication signals as well as the structures of the streets. This paper gives the results of simulations on delay spread for (1) a straight street having no reflection walls at either end, (2) a street that has a reflection wall at one end of the street (blind alley road), and (3) a street that has reflection walls at both ends. The simulation results show that the delay spread characteristics depend on the positions of the transmitting and the receiving points, and the structures of the street. Further more, it was found that the reflection wall facing the transmitting point has important influences on the delay spread characteristics.
