Abstract

Multi-path propagation structure in the urban mobile communication environment of 2.5 GHz band has been measured by means of nea ly developed "multi-path propagation parameter measurement equipment," which is capable of estimating coupled DOA (Direction Of Arrival), TOA (Time Of Arrival) and relative held strength by super resolution techniques. Be fore measurement, basicperformance of the equipment has been evaluated in the anechoic chamber inorder to ascertain limitation on measurement. For practice and verification of outdoor propagation characteristics, basic data have been collected ina works where accurate buildings and road layout is known. Subsequently, data have been collected in the urban mobile communication environment and following characteristics have been confirmed. 1) DOA and TOA of wave reflected by the side of building almost follow the ray-trace. 2) Street trees make 25 GHz band wave attenuate. 3) There are such unusual cases that it is possible to communicate in spite of out of line-of-sight by multi-path propagation. 4) Narrow streets have very complicated propagation structures. Finally, technologies that should be developed for the high-speed digital mobile communication are proposed based on the measurement results.
