1. A wireless communication system including a transmitter and a receiver that perform wireless communication using a single-carrier multi-value modulation scheme,
wherein the transmitter comprises
a transmission signal amplifier in which transmission power is variable and
the transmitter is configured to execute;
providing the receiver with a specification related to an input/output characteristic of the transmission signal amplifier; and
of providing the receiver with transmission power used for data transmission, and wherein
the receiver is configured to execute:
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.
