Forward error correction (FEC) scheme for communications. Appropriate selection/arrangement of bits of an information bit sequence undergo one or more types of subsequent encoding to generate a coded bit sequence that may subsequently undergo appropriate processing to generate a continuous time signal to be launched within a communication channel. In some embodiments, an information bit sequence, after being partitioning into a number of information bit groups, initially undergoes a first encoding within a first encoding module thereby generating a number of redundancy/parity bit groups (e.g., e.g., each redundancy/parity bit group corresponding to one of the information bit groups). Then, after performing any desired and appropriate selection/arrangement of bits within the redundancy/parity bit groups and the information bit groups, second encoding within a second encoding module is performed thereon to generate additional redundancy/parity bits. In addition, interleaving may be performing at various stages of the encoding processing. |
