摘要

Disclosed herein is a decoding apparatus for decoding an LDPC (Low Density Parity Check) code received in a first format or a second format wherein a process to decode received values each obtained as a result of receiving the LDPC code in the first or second format includes at least F check-node processes carried out concurrently as processes of F check nodes respectively or F variable-node processes carried out concurrently as processes of F variable nodes respectively.
