| Abstract: | A hard-decision decoding algorithm for LDPC code is proposed, which chooses error bits from received block based on the condition whether the parity-check functions are satisfied or not, and then flips these error bits. Then the sparse parity-check matrix is described and the construction of parity-check tree is introduced to analyze and describe the decoding algorithm. Finally, an implementation of decoding algorithm is given. |
