Mobile-link system for a radio communication system wherein diversity combining is performed only for edge/boundary zone signals and not for central zone signals |
摘要 |
A mobile-link system for a radio communication system including a first mobile-link assembly, a second mobile-link assembly, and a satellite feeder-link assembly located in a satellite; and an earth feeder-link assembly located in an earth station. The first mobile-link assembly receives mobile uplink signals including zone-one uplink signals transmitted from mobile stations located in a first zone of a coverage area and zone-two uplink signals transmitted from mobile stations located in a second zone of the coverage area, and outputs received zone-one uplink signals and received zone-two uplink signals. The second mobile-link assembly receives mobile uplink signals transmitted from mobile stations in the coverage area, and outputs received zone-two uplink signals and not zone-one uplink signals. The second mobile link assembly also transmits mobile downlink signals to at least the first and second zones of the coverage area. The satellite feeder-link assembly conveys the received mobile uplink signals to the earth feeder-link assembly by transmitting feeder-link downlink signals corresponding to the received mobile uplink signals. The earth feeder-link assembly is connected to and couples the mobile-link system to a communication network. The earth feeder-link assembly includes a combiner for combining the feeder-link downlink signals such that the zone-two uplink signals received by the first and second mobile link assemblies are combined to produce diversity resultant signals.
