Abstract
A receiving unit is more precisely synchronized to a transmitting unit by transmitting synchronization signals from the transmitting unit, adjusting a clock-pulse generator of a phase-locked loop, a phase shifter integrating instantaneous phase errors to an integration value, and adjusting the integration value to an integration fraction that is less than one.
Claims12
A synchronization method for a receiving unit, comprising the steps of:
- cyclically transmitting synchronization signals to the receiving unit from a transmitting unit;
- feeding the synchronization signals from the receiving unit to a phase shifter of a phase-locked loop having a clock-pulse generator;
- emitting a number of clock signals between two synchronization signals, the clock pulse generator emitting the number of clock signals;
- and
- upon reception of the synchronization signals by the phase shifter, detecting instantaneous phase errors and readjusting the clock-pulse generator so that the clock-pulse generator emits a predetermined number of clock signals between two synchronization signals, the phase shifter integrating the instantaneous phase errors to an integration value, the integration value being adjusted to an integration fraction less than one.
