发明名称 ADAPTIVE SUBCARRIER LOADING
摘要 A wireless multicarrier transmission method in which a multicarrier transmission uses n modulated frequency subcarriers (n is an integer number), and a fading condition of each subcarrier is detected to generate fading channel profile information. The modulation of each subcarrier includes selecting a standard modulation scheme, a lower modulation scheme, and a higher modulation scheme; selecting three integer numbers x, y, and z representing the number of subcarriers for modulation with the lower modulation scheme, with the standard modulation scheme, and with the higher modulation scheme respectively, the sum of x, y, and z is n and a resulting number of coded bits of a multicarrier symbol is constant; and modulating the x subcarriers having low fading channel profile information with the lower modulation scheme, modulating the y subcarriers having medium fading channel profile information with the standard modulation scheme, and modulating the z subcarriers having high fading channel profile information with the higher modulation scheme.
