Subscriber frequency control system and method in point-to-multipoint RF communication system

摘要: A point-to-multipoint star configured terrestrial radio communication system having at least one base station transmitting to and receiving RF signals from a plurality of associated subscriber stations in the 0.3-300 GigaHertz (GHz) range. The includes means for reducing frequency uncertainty, drift or error transmissions each station. Each has low cost local reference oscillator, incorporates broadcast signal high precision there is measuring compensating drift/error low-cost oscillator Moreover, can provide an estimate obtained relaying measured corresponding compensate that subscriber's transmitter's be out frequency.
