Abstract

En un método de comunicación de acuerdo con una modalidad de la presente invención es una contraseña, la cual se genera con base en los códigos de comprobación de paridad casi cíclicos que incluyen códigos de comprobación de paridad de baja densidad casi cíclicos de repetición-acumulación, se sujeta a una permutación de bloques cíclicos en donde el orden de los bloques cíclicos en esta contraseña se reorganiza, y cada bit de la contraseña que se ha sometido a la permutación de bloques cíclicos se correlaciona con un punto de constelación de una constelación no uniforme, mejorando de ese modo el desempeño de recepción.
