In the transmission device, a synchronization pattern made by arranging a predetermined basic pattern consisting of a combination of a predetermined number of symbols and a reversal basic pattern made by reversing a polarity of each symbol of the basic pattern, in the order according to a reversal pattern, is generated, and transmission data obtained by adding thus obtained synchronization pattern at predetermined timing is transmitted. In the reception device, the basic pattern and reversal basic pattern in the synchronization pattern are correlated with each other by a matched filter (11) corresponding to the basic pattern, and the correlation of the reversal pattern which appears in a signal obtained as a result, is taken by a matched filter consisting of delay portions (12), multipliers (13) and an adder (14). <IMAGE> |
