    Abstract: Provided is an apparatus and method for separating two phase-modulated signals having different amplitudes. A separation method for a phase-modulated signal may include: receiving, using a single antenna, a first received signal and a second received signal that are modulated and thereby transferred from a transmitter; calculating an attenuation level of each of the first received signal and the second received signal by dividing each of the first received signal and the second received signal into a real number portion and an imaginary number portion; calculating a difference between the first received signal and the second received signal; and separating and thereby demodulating the first received signal and the second received signal.
