Abstract
APARELHO E MÉTODO PARA CODIFICAÇÃO DE MÚLTIPLOS NÍVEIS. A presente invenção se refere a um aparelho e método para codificação de múltiplos níveis de uma sequência de mensagem de entrada em uma sequência de símbolo, por exemplo, com base em codificação polar. A mensagem de entrada compreende bits de informações. O aparelho é configurado para dividir a mensagem de entrada em uma pluralidade de submensagens, codificar cada uma das submensagens em uma palavra-código, em que um conjunto das submensagens é codificado com base nas palavrascódigo obtidas codificando-se as submensagens que não estão no conjunto e em uma função predefinida da sequência de símbolo, e mapear as submensagens codificadas em símbolos correspondentes.
