Abstract
A method for demapping a multicarrier signal into soft bits by a receiver, comprises the steps of: calculating signal to noise ratio ('SNR') adjustment factors ('A[segidx]') for segments of the signal, wherein each of the segments has a predefined number of subcarriers of the signal; generating an adjusted SNR (“SNR[segidx]”) as a function of an average SNR over the subcarriers of the signal and of the calculated SNR adjustment factors; and determining the soft bits for the signal as a function of the signal, a channel estimation for the signal, and the adjusted SNR, wherein the receiver decodes the determined soft bits.
