Abstract :
A frame synchronization is presented that is included in time-variant coded modulation without any loss in data rate. It delivers the phase offset to control the carrier loop. Time-variant coded modulation based on block codes is defined. There is no need for additional sync-headers. A detailed derivation of the corresponding probabilities to be out of sync has been included to simplify the selection of sync-sequences for a special application
