METHOD AND SYSTEM FOR MAPPING BIT SEQUENCES

摘要

A method of mapping a plurality of different bit sequences (u) to a plurality of different signal points (x) in a constellation, the number of bit sequences (u) being greater than the number of signal points (x), said method comprising, for a device in a telecommunication network, the acts of: - determining, for each signal point (x) in the constellation, a number of bit sequences (u) to be mapped to said each signal point (x), the numbers of bit sequences (u) being distributed according to a discrete Gaussian distribution among the constellation, - selecting in the plurality of bit sequences (u), f o r e a c h s i g n a l p o i n t (x) in the constellation, a set comprising the determined number of bit sequences (u) that minimize the maximal Hamming distance among the selected sets.
