Abstract
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−1)th iteration; obtaining a first energy summation of the first belief values; obtaining second belief values of the message in an ith iteration; 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.
