发明名称 Time-synchronous communication system
摘要 A time-synchronous communication system comprises: fixed stations having distance measuring/time reference synchronization and maintaining unit, receiving/processing unit, transmitting/processing unit, and communication data processing management unit; mobile stations having distance measuring/time reference synchronization and maintaining unit, transmitting/processing unit, receiving/processing unit, and communication data processing management unit; and relay stations having distance measuring radio wave transmitting/processing unit, time reference synchronization and maintaining unit, and radio wave relay unit for relaying transmission radio waves from the fixed stations and the mobile station. Each mobile station selects a specific fixed station communication radio wave from communication radio waves transmitted from the fixed stations by determining a mobile station reception timing to perform receiving/processing operation, and selects specific relay and fixed stations from the relay stations and the fixed stations by controlling a mobile station transmission timing to be synchronized with a reception timing determined by the specific fixed station to perform communication.
