A wireless communication device has a plurality of antennas and has MIMO functions that receive a plurality of spatially multiplexed signal sets, perform an inverse matrix computation using SN ratios of the plurality of the signal sets, based on a transfer function of a transmission path of the plurality of the signal sets, decode a first encoded signal in which is encoded the plurality of the signal sets on which the inverse matrix computation was performed, and output a decoded signal. The wireless communication device includes an encoder that generates a second encoded signal by encoding the decoded signal and a control portion that, if one of the SN ratio and the difference between the first encoded signal and the second encoded signal does not meet a specified standard, shifts the wireless communication device to a reduced power consumption state in which the amount of electric power that is consumed is reduced.
