Abstract
Provided is a turbo decoder with a variable scaling factor. The decoding convergence degree of the turbo decoder is evaluated using a sign difference ratio (SDR) value, the iterative-decoding number is limited, a variable scaling factor is calculated and applied in each decoding convergence area based on the SDR value, and the average number of decoding iterations is reduced.
