Abstract

"método e aparelho para o mapeamento de um fluxo de bits". é revelado um método e aparelho para mapear um fluxo de bits emitidos de um codificador para um fluxo de bits para a modulação 2^ m^-ária. o método e aparelho divide o fluxo de bits do codificador em um primeiro período e um segundo período. o primeiro período inclui bits com prioridade mais alta no fluxo de bits emitidos do codificador, e o segundo período inclui bits com prioridade mais baixa. o método e aparelho mapeia os bits existentes no primeiro período à posições de bits com confiabilidade mais alta em um fluxo de m bits que representam cada um dos bits para a modulação 2^ m^-ária, e mapeia os bits existentes no segundo período às posições de bits com confiabilidade mais baixa no fluxo de m bits.
