PROBLEM TO BE SOLVED: To avoid inconvenience of data interruption during communication by allowing a receiver side to discriminate the sequence of serial parallel conversion at a transmitter side and a start position of reception data of plural lines. SOLUTION: A data output of a mobile station transmitter-receiver 11 is given to a unique word detection circuit 12 to detect the sequence of patterns outputted from a unique word pattern generator 5 or a unique word pattern generator 5' at the transmitter side and a pattern bit start position at a high speed. A data output of a mobile station transmitter-receiver 11' is given to a delay circuit 13 to arrange unique word detection positions for plural lines, the arranged words are given to a changeover circuit 26. The changeover circuit 26 selects reception data of the transmitter-receiver 11 or reception data of the transmitter-receiver 11' so that the input sequence of a control means demultiplexer circuit 14 so that is sequence of data signals of a transmission 1 system in 32kb/s and a transmission 2 system in 32kb/s, and a multiplexer/ demultiplexer circuit 14 are used for the reception data to restore data in 64kb/s in the order of parallel serial conversion at the transmitter side.
