Abstract

See full text

A wireless communication device includes: a transmitting circuit that is connected to an antenna and includes a power amplifier that amplifies an input signal; a receiving circuit that is connected to the antenna and includes a switch that switches as to whether or not a signal is received; and a processor that executes a process including: acquiring timing information that indicates timing of a guard period when no signal is transmitted or received by the antenna; turning on the power amplifier and turning on the switch in the guard period based on the acquired timing information to input a noise signal of the transmitting circuit that is amplified by the power amplifier to the receiving circuit; measuring electrical power of a signal that is output from the receiving circuit in the guard period; and determining abnormality of the receiving circuit based on the measured electrical power.
