- The strongest ray analysis based on the computer simulation of wave propagation between a base station(BS) and mobile stations(MSs) is carried out to obtain the spatial-time wideband channel characteristices. The stronest rays are reponsible for about 70% of the total received power for BS-MS pairs on the average and their arrival angles rarely deviate from the shortest path lices between a BS and MSs. However, this does not mean that the strongest ray is necessarily the first arrived ray for each BS-MS pair. The AOA statistics reveal that AOAs of the strongest and the second strongest rays are very close each other for uplink channel, while those are quite apart for downlink channel.
