Abstract

Se proporciona un transmisor. El transmisor incluye: un codificador de Comprobación de Paridad de Baja Densidad (LDPC) configurado para codificar bits con codificación exterior para generar una contraseña de LDPC que incluye bits de información de LDPC y bits de paridad; un perforador configurado para perforar algunos de los bits de paridad incluidos en la contraseña de LDPC; y un mapeador configurado para mapear la contraseña de LDPC excepto los bits de paridad perforados a símbolos para la transmisión a un receptor, en donde el perforador calcula un número de bits de paridad que se perforarán entre los bits de paridad incluidos en la contraseña de LDPC con base en un número de los bits con codificación exterior, un número de los bits de información de LDPC y un número mínimo de bits de paridad que se perforarán entre los bits de paridad incluidos en la contraseña de LDPC.
