Abstract
In a transmission circuit that transmits transmission data using an amplitude shift modulation method (ASK modulation method) for changing an amplitude of carrier waves based on the transmission data or a transmission system that uses the transmission circuit, a phase of the carrier waves is changed based on the transmission data to suppress an irradiation of carrier wave components.
Claims11
A transmission circuit, comprising:
- a phase control circuit configured to change a phase of carrier waves based on transmission data and output the carrier waves;
- and
- an amplitude shift modulation circuit configured to change an amplitude of the output carrier waves.
A transmission method, comprising:
