摘要: PROBLEM TO BE SOLVED: To provide a demodulation apparatus capable of suitably correcting the distortion signal. SOLUTION: A signal method includes peak position calculation step (S100) for finding out in constellation map (signal point drawing) received signal, boundary (S200) demodulating based on found step, and decoding (S300) by using step.
