Reception device, control method, and program |
摘要 |
A reception device that receives a modulation signal being a result of digital modulation of a carrier is disclosed. The device includes: a demodulation section that demodulates the modulation signal into a demodulation signal including an I component and a Q component; a numerically controlled oscillation section that generates a signal of predetermined phase; a phase error detection section that detects a phase error between a phase of a symbol of the demodulation signal and the predetermined phase of the signal generated by the numerically controlled oscillation section; a phase rotation section that rotates the phase of the symbol of the demodulation signal in accordance with the phase error; a loop filter that filters the phase error, and controls the numerically controlled oscillation section; and a gain control section that controls a gain of the loop filter based on a modulation technique of the modulation signal. |
