<p>PURPOSE:To provide a radio communication system having practically sufficient secrecy capable of making a circuit scale small, making an equipment small in size and low in cost and eliminating the malfunction of a synchronization processing due to interference or the like. CONSTITUTION:A transmitter 1 transmits transmission signals for which Barker codes are added to data from an antenna 16, a receiver 2 receives the data to which the barker codes are added through the antenna 21, the autocorrelation value of the Barker codes is detected by a code correlation device 25 to be defined as synchronizing signal detection and a clock generator 26 is activated. Thus, reception data delayed for the operation delay of the code correlation device 25 by a delay device 27 are sampled and outputted by a data sampler 28 in synchronism with the clocks of the clock generator 26. At the time, when synchronizing signals are detected, the code correlation device 25 stops the operation until a counter 31 counts the clocks for one burst and prevents erroneous synchronization due to the interference or the like.</p> |
