Abstract
A demodulation device includes a phase rotation module, a phase adjustment module, a phase comparison module, and a reference signal generation module. The phase rotation module rotates phases of an I-Phase signal and a Q-Phase signal in a received signal of a multilevel PSK signal using a reference signal. The phase adjustment module adjusts the phases of the phase rotated I-Phase signal and the phase rotated Q-Phase signal output from the phase rotation module by multiplying the phases of the I-Phase signal and the Q-Phase signal with an integer value to generate a phase adjusted I-Phase signal and a phase adjusted Q-Phase signal. The phase comparison module compares the phase of the phase adjusted I-Phase signal with the phase of the phase adjusted Q-Phase signal to generate a phase comparison result. Also, the reference signal generation module generates a reference signal using the phase comparison result.
