Abstract:
An iterative decoding device includes a decoder, a dual mode determination unit and a dual mode scaling unit. The decoder is utilized for receiving a set of soft information (SI) and iteratively decoding the set of SI and updating the set of SI accordingly to generate a set of updated SI. The dual mode determination unit is coupled to the decoder for generating a determination result according to the set of updated SI. The dual mode scaling unit is coupled to the dual mode determination unit and the decoder for scaling the set of updated SI according to the determination result to generate a set of scaled SI acting as an input of the decoder for next iteration.
