ERRONEOUS SYNCHRONIZATION PREVENTION ALGORITHM AND RADIO COMMUNICATION EQUIPMENT

PROBLEM TO BE SOLVED: To establish synchronization in a short period of time without generating erroneous synchronization in radio communication equipment using a TDD communication method. SOLUTION: A master side communication machine transmits a signal to a slave side communication machine by alternately adding a correct signal and a dummy signal to control data of a synchronization request signal, in each frame, to be transmitted from the master side communication machine to the slave side communication machine. If the slave side detects a dummy SYNC signal in the first frame, the slave side adds a synchronizing signal counter, if the slave side can not detect synchronizing signal data in the next frame, the slave side subtracts a count value (CT), and since the slave side decides that synchronization is established if the slave side subsequently and continuously detects synchronizing signal data, the slave side eliminates the influence of the dummy SYNC signal and establishes synchronization in a short period of time without generating erroneous synchronization.
