Wireless communication system, wireless communication method, and reception apparatus

A wireless communication method using a transmitter and a receiver that perform wireless communication using a single-carrier multi-value modulation scheme,

• wherein the transmitter includes a transmission signal amplifier in which transmission power is variable, and
• the wireless communication method includes:
• providing, by the transmitter, the receiver with a specification related to an input/output characteristic of the transmission signal amplifier;
• providing, by the transmitter, the receiver with transmission power used for data transmission;
• estimating, by the receiver, a constellation of signal points on the basis of the transmission power and the specification;
• detecting, by the receiver, a reception point of a reception signal, the reception point being a point in constellation coordinates;
• calculating, by the receiver, likelihood for the reception point, with respect to the signal points;
• and
• identifying, by the receiver, a symbol intended by the reception point on the basis of a result of the likelihood calculation.

A receiver for performing wireless communication using a single-carrier multi-value modulation scheme, the receiver being configured to execute:

• acquiring, from a transmitter for the wireless communication, a specification related to an input/output characteristic of a transmission signal amplifier used by the transmitter;
• acquiring transmission power used for data transmission by the transmitter;
• estimating a constellation of signal points on the basis of the transmission power and the specification;
• detecting a reception point of a reception signal, the reception point being a point in constellation coordinates;
• calculating likelihood for the reception point, with respect to the signal points;
• and
• identifying a symbol intended by the reception point on the basis of a result of the likelihood calculation.
