Abstract
A radio system broadcasts binary data packets that can be received in mob receivers. The initial parts of the packets are transmitted periodically. The prefix of each packet includes synchronizing information. The synchronization processing includes seeking a phase and a tracking phase. The transition from the seeking to the tracking phases occurs when the synchronization pattern has been received two consecutive times with a null Hamming distance.
