  • Method and arrangement for compensating shifts in delay produced by the doppler effect in bursts in a TDMA frame
    Patent number: 4872164
    Abstract: A method for compensating for shifts in delay caused by the Doppler effect in the bursts from ground stations when received by a transponder satellite, wherein a search is made within the bursts for agreed-upon bit patterns. Then a phase comparison is made between the system clock pulse of the satellite and the clock pulse recovered from the bursts, with the point in time of this phase comparison being derived from the finding of the bit pattern. Depending on the result of the phase comparison, the burst are now delayed to a greater or lesser extent.
