Abstract
De acuerdo con algunas modalidades, un método para usarse en un transmisor inalámbrico de una red de comunicación inalámbrica comprende codificar bits de información usando una matriz de verificación de paridad (PCM) y transmitir los bits de información codificados a un receptor inalámbrico. La matriz de verificación de paridad (PCM) es optimizada de acuerdo con dos o más restricciones de grado de mensaje extrínseco de ciclo aproximado (ACE). En algunas modalidades, una primera porción de la PCM se optimiza de acuerdo con una primera restricción de ACE y una segunda porción de la PCM se optimiza de acuerdo con una segunda restricción de ACE.
