Abstract
A forward error correction decoder for packing error information of a codeword in the space that was previously occupied by the parity symbols in the decoder output is presented. Specifically, the decoder summarizes error information of the codeword in a summary vector having the size no greater than the total size of the parity symbols. The decoder then outputs the message symbols from the codeword and the summary error vector, which provides the error information of the received codeword but only requires a bandwidth that is no greater than the bandwidth previously used for transmitting the parity symbols.
