Abstract
A decoding apparatus and method. When all the code words in the to-be-decoded group meet that a checksum is 0, forward error correction (FEC) decoding is not performed, and only the sign bit decision is performed. That is, in a process of performing multiple times of decoding on each code word, FEC decoding is not always performed every time. This reduces power consumption required by FEC decoding.
