Abstract
The present invention provides a constellation mapping method, and the method includes: flipping a plurality of bits in each modulation symbol unit to be mapped in part of or all of modulation symbol units to be mapped of a bit sequence to be mapped; and mapping each flipped modulation symbol unit to be mapped as a modulation symbol in a constellation. By means of the present invention, the phenomenon that consecutive bits have the same reliability can be effectively avoided by changing unevenness of reliability distribution of the consecutive bits, and at the same time, the link performance can be improved.
