US 10,256,869 B2 · Communication apparatus and communication method

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.

Dependent claims

A communication apparatus comprising:

a test signal generating section configured to generate a predetermined test signal;
a detecting section configured to detect an influence parameter affecting the intensity of an active load modulation signal that combines a transmission carrier transmitted by another communication apparatus and received by a transmitting and receiving section with a synchronizing signal transmitted by the transmitting and receiving section in synchronism with a received signal obtained upon receipt of the transmission carrier, the influence parameter being detected from a received test signal obtained upon receipt of the test signal;
and
a controlling section configured to control the intensity of the active load modulation signal in accordance with the influence parameter.
