Abstract
In a radio communication method whereby adaptive modulation is performed, a method is used whereby pilot symbol signal points are arranged in the in-phase-quadrature plane (IQ plane) so that the reception sensitivity of a receiving apparatus is made optimal in the respective modulation methods while maintaining the average transmission output power of the transmitting apparatus at a fixed level. By this means, it is possible to arrange pilot symbol signal points and improve the reception sensitivity characteristics of a receiving apparatus while maintaining the average transmission output power of the transmitting apparatus at a fixed level.
