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.

Iterative decoding device and related decoding method for irregular low-density parity-check code capable of improving error correction performance

A decoding method for low density parity check (LDPC) and an electric device using the decoding method are provided. The decoding method includes: receiving a message and executing an iteration decoding to the message; obtaining first belief values of the message in an (i&#x2212;1)iteration; obtaining a first energy summation of the first belief values; obtaining second belief values of the message in an iiteration; obtaining a second energy summation of the second belief values; determining whether the second energy summation is smaller than the first energy summation and whether a difference between the first energy summation and the second energy summation is larger than a first threshold; if yes, generating a decoding result according to the first belief values. Therefore, a bit error rate of the decoding is decreased.
