Abstract
"DISPOSITIVO DE CODIFICAçãO DE BANDA LARGA, DISPOSITIVO DE PREDIçãO DE LSP DE BANDA LARGA, DISPOSITIVO DE CODIFICAçãO DE BANDA ESCALONáVEL, MéTODO DE CODIFICAçãO DE BANDA LARGA". A presente invenção refere-se a um dispositivo de predição de LSPs de banda larga e outros capazes de predizer um LSPs de banda larga de um LSPs de banda estreita com uma alta eficiência de quantização e uma alta precisão, ao mesmo tempo em que suprime o tamanho de uma tabela de conversão, correlacionando o LSPs de banda estreita com o LSPs de banda larga. Nesse dispositivo, uma unidade de predição não-linear (102) realiza predição não-linear pelo uso de um LSPs de banda larga convertido introduzido de uma unidade de conversão de banda estreita/ banda larga (101) e introduz o resultado da predição não-linear em um amplificador (103). O LSPs de banda larga convertido é introduzido em um amplificador (104). Um somador (122) adiciona os resultados da multiplicação (vetores) introduzidos dos amplificadores (103, 104).
