摘要： Provided is a low-complexity and low-power-consumption turbo decoder with a variable scaling factor. The performance of the turbo decoder is enhanced by evaluating a decoding convergence degree of the turbo decoder using a sign difference ratio (SDR) value, limiting the iterative-decoding number, and calculating and applying a variable scaling factor producing optimal performance in each decoding convergence area based on the SDR value, and power consumption is reduced by reducing the average number of decoding iterations. Thus, the performance degradation when the encoded block is large, which is a shortcoming of a conventional EMLMAP algorithm, can be prevented, the average number of decoding iterations can be reduced, and accordingly power consumption can be reduced.
