Abstract
A communication system includes a transmission device that transmits a signal, based on a plurality of symbol coordinates on a constellation, which characterize a shape having a predetermined rotational asymmetrical shape, and a receiving device that accumulates symbol coordinates on the constellation in the signal received from the transmission device and estimates the phase of the signal received from the transmission device, based on a difference between the direction of a shape characterized by the accumulated symbol coordinates and the direction of the predetermined shape.
