In order to enable the use of less sophisticated frequency synthesizer in mobile stations (UT 1) of a satellite mobile telephone network, without increasing the time required to find a network, broadcast control channel (BCCH) signals are pre-compensated for Doppler shift. The pre-compensation means that the BCCH for a cell will always fall within the receiver bandwidth of a mobile station (UT 1) tuned to the nominal BCCH frequency. |
