FREQUENCY DRIFT CORRECTION IN SUBSCRIBER TERMINALS |
摘要 |
A frequency control system and method for minimizing frequency drifts in subscriber terminals in a point-to-multipoint system is described enabling the use of low cost oscillators (5) in the subscriber terminals by measuring the frequency offset (9) of the subscriber terminal's receiver to estimate its oscillator frequency drift which is then used to correct the subscriber terminal's transmitter (12) frequency and also by feedback of a frequency correction from the base station to the subscriber.
