Abstract

um método para gerar um sinal-alvo de banda alta inclui receber, em um codificador, um sinal de entrada que tem uma porção de banda baixa e uma porção de banda alta. o método também inclui comparar um primeiro valor de autocorrelação do sinal de entrada com um segundo valor de autocorrelação do sinal de entrada. o método inclui adicionalmente escalonar o sinal de entrada por um fator de escalonamento para gerar um sinal de entrada escalonado. o fator de escalonamento é determinado com base em um resultado da comparação. o método também inclui gerar um sinal de banda baixa com base no sinal de entrada e gerar o sinal-alvo de banda alta com base no sinal de entrada escalonado.
