PROBLEM TO BE SOLVED: To provide a method, a device and a system for multicarrier modulation signal bit allocation.SOLUTION: A multicarrier modulation signal bit allocation method comprises; a determination step for determining a signal-to-noise ratio (SNR) margin on the basis of a probability of maximum clipping noise allowed by a preset system; and an allocation step for allocating the number of modulation bits and electric power in each subcarrier for multicarrier modulation signals on the basis of the SNR margin. Presetting the SNR margin for the clipping noise increases the tolerance to the signal clipping noise, effectively reducing the bit error rate.SELECTED DRAWING: Figure 1 |
