| 25 | 4 | COLIN, Tony | Hence, encoding stands for *O(nbytes x NPAR)* with _nbytes_ is the codeword length, _NPAR_ the number of parity bits. |
| 26 | 4 | COLIN, Tony | Since it is a systematic code _nbytes = information_word_length + NPAR_ encoding stands for *O(information_word_length)* with NPAR constant. |
