<p>A communication method using M signal points arranged on the I-Q plane so as to improve the characteristics of communication. The M signal points are arranged on the I-Q plane at regular intervals a both in the I-axis and Q axis directions, centering the origin of the I-Q plane, in such a way that within a circle the radius of which is the distance b between a point having the maximum values both in the I-axis and Q-axis directions and the origin, or within the circle and on its periphery, the distance between arbitrary two signal points is longer than the regular intervals a and the distance between at least one set of signal points is longer than the regular intervals a.</p> |
