<p>PROBLEM TO BE SOLVED: To obtain a receiving device whose receiving performance is improved.SOLUTION: A receiving device in a communication system to which a differential modulation system is applied includes: a differential demodulation unit 3 for demodulating a receiving signal and generating a first demodulation signal; a temporary determination unit 4 for determining the first demodulation signal and generating a first determination value; a differential modulation unit 5 for differentially modulating the first determination value and generating a reference signal; a filter unit 6 for filtering the receiving signal by a filter coefficient based on the reference signal and generating an interference-suppressed signal; a differential demodulation unit 7 for demodulating the interference-suppressed signal and generating a second demodulation signal; a determination unit 8 for determining the second demodulation signal and generating a second determination value; and a selection unit 9 for selecting either one of the first determination value and the second determination value.</p> |
