A wireless communication apparatus includes an amplifying unit that amplifies an input signal that includes signals with different frequencies of a first frequency and the second frequency; a measuring unit that measures a level of inter modulation distortion generated in a signal obtained by the input signal being amplified by the amplifying unit; a determining unit that determines whether the level of the inter modulation distortion measured by the measuring unit is equal to or greater than a regulation value that is previously stored; and a control unit that decreases, when a result of the determination obtained by the determining unit indicates that the level of the inter modulation distortion is equal to or greater than the regulation value, a level of a signal input to the amplifying unit.

Wireless communication apparatus, communication control method, and computer-readable recording medium

In a wireless communication device, in a correction value calculating mode, a control unit flips switches to the 'a' sides, a modulation processing unit generates a CW signal as an I channel signal, a DAC converts the digital CW signal into an analog CW signal, an LPF eliminates the high-frequency component from the CW signal, a mixer functions as an up-converter for up-converting the CW signal, a PA amplifies the RF power of the CW signal, a mixer functions as a down-converter for down-converting the CW signal, an ADC converts the analog CW signal into a digital CW signal, a level detecting unit detects the voltage level of the CW signal, a correction value calculating unit calculates a correction value based on the detected voltage level, and a correction value storing unit stores the calculated correction value.
