<P>PROBLEM TO BE SOLVED: To provide a demodulating device which corrects a symbol position of transmission data. <P>SOLUTION: The demodulating device corrects the symbol position composing the received transmission data to a proper position, and performs demodulation, based on the transmission data whose symbol position is corrected. A frame synchronization circuit performs frame synchronization establishment processing when the frame synchronization is established, transmits the signal to a frame synchronization monitor, and notifies that the frame synchronization is established. Moreover, the frame synchronization circuit calculates deviation of the symbol position of the transmission data from a decided position, and transmits a reference signal including the deviation information to a rotation circuit. The rotation circuit recognizes the deviation amount of the symbol position from the reference signal, and corrects the symbol position of the transmission data. <P>COPYRIGHT: (C)2007,JPO&INPIT |
