Abstract: This paper gives the theoretical mechanism of decoding of low density parity check(LDPC) codes with belief propagation algorithm,based on which a serial decoding architecture with comparatively easy addressing scheme is introduced.Performance and implementation complexity are presented as well.It turns out that the solution makes addressing easier and thus saves the resource.It is also suitable to general regular LDPC codes.
