Abstract
A system includes an encoder that manipulates postcoded data and produces parity bits, and a parity bit encoder that produces encoded parity bits by inserting into the parity bits one or more flags with polarities, or states, that are selected to produce, after precoding, precoded parity bits that meet predetermined modulation constraints.
