Abstract

A method of decoding low-density parity-check codes comprises a first step that includes calculating └└rRml, for each parity check equation, at iteration i−1, in response to a third step. A second step includes decision aided equalizing, at iteration i, in response to the first step. The third step includes calculating └└rQ└m, for each parity check equation, at iteration i in response to the second step, wherein └└rQ└m represents information from bit node l to equation node m, one for each connection, and wherein └└rRml represents information from equation node m to bit node l, one for each connection.
