Wireless communication device and apparatus

Abstract

When performing contactless communication, occurrence of error in data determined on the receiving side due to attenuation of a wireless signal is prevented on both receiving sides by using a simple configuration. Provided is a wireless communication device including: a transmitting unit provided on a first member and a receiving unit provided on a second member and located at a varying relative distance to the transmitting unit, the transmitting unit generates a first electric signal obtained by superimposing a pilot signal on a digital signal to be transmitted and transmits a wireless signal having an intensity in accordance with the first electric signal, the receiving unit generates a second electric signal in accordance with the intensity of the received wireless signal and detects a pilot signal component from the second electric signal, and the second electric signal is amplified in accordance with an attenuation amount of the pilot signal component.
