Low Density Parity-Check (LDPC) codes achieve the best performance when they are decoded with the sum-product (SP) algorithm. This is a two-phase iterative algorithm where two types of messages are interchanged and updated ...

This paper proposes a low-complexity min-sum algorithm for decoding low-density parity-check codes. It is an improved version of the single-minimum algorithm where the two-minimum calculation is replaced by one minimum ...
