Inventor: MIZUNO KOTARO
IPC: H04L27/14
Filed: 2011-05-18
Abstract: PROBLEM TO BE SOLVED: To provide a signal demodulation method and device which can accurately demodulate a digital modulation signal.SOLUTION: A digital modulation signal as an input signal is detected to generate a detection signal, and the generated detection signal is delayed by an amount equal to one symbol to generate a delay signal. The timing at which a difference in analog signal level between the detection signal and the delay signal becomes zero is detected as zero-cross timing. A determination threshold is obtained based on an analog signal level of the detection signal at the zero-cross timing, and the obtained value is retained. On the basis of comparison between the analog signal level of the detection signal and the determination threshold, a current symbol value which the detection signal indicates is output as demodulation output.
