Abstract
In a communication system, a base station (1) transmits to a mobile station (5) in different channels. One channel is relayed to the mobile station (5) by a first satellite (3) and the other is relayed by a second satellite (4). The mobile unit (5) compares the qualities of the signals relayed by the satellites (3, 4) and transmits back to the base station (1) using the satellite (3,4) providing the best quality signals. The use of satellite links is not essential. The system has the advantages of diversity communication without increasing power demand at the mobile station.
