TDMA SYSTEM TIMER FOR MAINTAINING TIMING TO MULTIPLE SATELLITE SIMULTANEOUSLY

摘要

A method for timing correction in a communications receiver includes the steps of (a) setting a timer (114) to a known value; (b) defining a first window (402) by defining a first rollover value; (c) defining a second window (404) by defining a second rollover value; (d) defining a first receive gate transition (434) relative to the first rollover value; (e) defining a second receive gate transition (436) relative to the second rollover value; (f) starting the timer (114); (g) receiving (110) a first receive burst (410) in the first window; (h) receiving (110) a second receive burst (410) in the second window. The rollover values are increased or decreased depending on whether the receive bursts are received before or after the receive gate transitions.
