PROBLEM TO BE SOLVED: To provide bit assignment method, device and system of multicarrier modulation signal.SOLUTION: On the basis of the previously installed total number of bits, the number of bits of subcarriers of a multicarrier modulation signal, to which the maximum number of bits is assigned, is reduced. More specifically, the method sets the total number of bits for adjustment, determines a target number of bits on the basis of the total number of bits for adjustment, assigns the number of bits by each subcarrier of the multicarrier modulation signal on the basis of the target number of bits by a predetermined bit assignment method, and reduces the number of bits of subcarrier of minimum average power, out of the subcarriers to which the maximum number of bits is assigned, until the total number of bits thus reduced is equal to the total number of bits for adjustment.SELECTED DRAWING: Figure 1 |
