  • Publication number: 20180287669
    Abstract: This technology relates to a communication apparatus and a communication method adapted to improve the deterioration of communication performance due to variations in parts, for example. A test signal generating section generates a predetermined test signal. A detecting section detects, given a received test signal obtained by a transmitting and receiving section upon receipt of the test signal, an influence parameter affecting the intensity of an active load modulation signal that combines a transmission carrier with a synchronizing signal synchronized with a received signal obtained upon receipt of the transmission carrier. A controlling section controls the intensity of the active load modulation signal in accordance with the influence parameter. This technology applies to cases where short-range wireless communication is performed using magnetic fields.
