This wireless receiving device is provided with a receiving means which generates a digital signal on the basis of a received signal, and a receiving method setting means which measures the signal quality of the digital signal generated on the basis of the received signal and generates a measured signal quality, selects a receiving method of the received signal by comparing a preset reference signal quality and the measured signal quality and generates a method selection signal, and, when the signal quality changes, generates and outputs a control signal depending on the method selection signal, wherein the receiving method is switched to a method in which power consumption changes depending on the control signal. This wireless receiving device can be adapted to multiple wireless methods, switches the receiving method depending on the reception environment, and can operate with low power consumption while securing reception performance. |
