Abstract
"MéTODO E APARELHO PARA APRIMORAR A QUALIDADE DE áUDIO PARA VOZ DIGITALIZADA TRANSMITIDA POR UM CANAL QUE EMPREGA A DIVERSIDADE DE FREQüêNCIA". A invenção descreve um aparelho e o método correspondente em um dispositivo móvel sem fio (10) para classificar cada um de uma pluralidade de bits de áudio obtidos de um codificador de voz (104) dentro de uma classe de uma pluralidade de classes de acordo com a importância predeterminada de cada bit de áudio, em que cada uma da pluralidade de classes tem um processo de correção de erro associado e um processo de diversidade de repetição associado. A correção de erro e a diversidade de repetição são aplicadas a uma parcela da pluralidade de classes com base nos processos de correção de erro e de diversidade de repetição associados. O método poderá ser implementado por um processador (10) que executa rotinas armazenadas em uma memória (110).
