摘要： 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.

摘要： A transmitting apparatus includes a modulation signal generating section that generates a modulation signal by modulating transmission data using one of a plurality of modulation schemes. The plurality of modulation schemes include a first modulation scheme, a second modulation scheme, and a third modulation scheme, where the first modulation scheme has maximum m-ary modulation value, the second modulation scheme has a lower m-ary modulation value than the first modulation scheme, and the third modulation scheme has a lower m-ary modulation value than the second modulation scheme. The transmitting apparatus also includes a pilot signal generating section that generates a pilot signal having one of a plurality of amplitudes, the pilot signal having a lower amplitude than a maximum amplitude of the first modulation scheme. The transmitting apparatus further includes a selection section that selects the modulation signal or the pilot signal according to a frame timing signal and generates a transmission quadrature baseband signal, a radio section that converts the transmission quadrature baseband signal to a radio signal, an amplifying section that amplifies the radio signal, and an antenna section that transmits the amplified radio signal.
