Abstract
In one embodiment a wireless communication device is provided that: acquires a phase rotation angle in the propagation channel which phase rotation angle is contained in a received symbol and that performs rotation compensation of the acquired phase rotation angle for the received symbol; generates a coordinate value of the respective I, Q axis in the signal constellation on which the information of the respective reference signal point is set; for the respective transmission bit, obtains respective probabilities that the transmission bit is 0 and 1 by making a distance determination of the distance between the received symbol after the rotation compensation and the respective reference signal level on only one of the I and Q axes; and makes a likelihood determination of the bit value of the respective transmission bit in accordance with a probability value obtained.
