BIT ALLOCATION METHOD, APPARATUS FOR MULTICARRIER MODULATION SIGNAL, AND SYSTEM

摘要

A bit allocation method, apparatus for a multicarrier modulation signal and a system where the method includes: lowering the number of bits of a subcarrier of minimum average power in subcarriers of the multicarrier modulation signal allocated with a maximum number of bits according to a predetermined total number of bits to be adjusted including setting a total number of bits to be adjusted; determining a target number of bits according to the total number of bits; allocating a bit number for each subcarrier of the multicarrier modulation signal by using a predetermined bit allocation method according to the target; and lowering the number of bits of a subcarrier of minimum average power in the subcarriers allocated with a maximum number of bits, until a lowered total number of bits is equal to the total number of bits to be adjusted.
