ABSTRACT:
In a demodulation device for processing a received data including a predetermined pattern, at each m bits, a bit pattern including the predetermined pattern is set, and the received data is shifted by one bit each time. A result of the shift is compared with the set bit pattern each time shifting is performed. The result of the shift is output in the case where coincidence is obtained. In the case where coincidence cannot be obtained, comparison is continued.
