<P>PROBLEM TO BE SOLVED: To provide a receiving device that suppresses the increase of a circuit scale. <P>SOLUTION: The receiving device is to apply delayed detection to a received signal which is differentially encoded, and includes a channel selection filter part 1 to suppress an interference component outside the transmission band of the received signal, a phase difference detecting part 2 to generate a complex signal having a phase difference between the received signal and a signal received one time before the received signal as an angle of deviation by performing signal conversion processing using code determination, code conversion, bit shift, and addition and substraction on the I component and Q component of the received signal obtained after the interference components are suppressed, and a demodulating part 3 to generate decoded data based on the generated complex signal. <P>COPYRIGHT: (C)2010,JPO&INPIT |
