Abstract

um método para processar um sinal de difusão de áudio digital em um receptor de rádio, inclui: receber um sinal de difusão híbrido; demodular o sinal de difusão híbrido para produzir um fluxo de áudio analógico e um fluxo de áudio digital; e usar uma correlação cruzada normalizada de envelopes do fluxo de áudio analógico e do fluxo de áudio digital para medir um deslocamento de tempo entre o fluxo de áudio analógico e o fluxo de áudio digital. o deslocamento de tempo pode ser usado para alinhar o fluxo de áudio analógico e o fluxo de áudio digital para a combinação subsequente de uma saída do receptor de rádio do fluxo de áudio analógico com a do fluxo de áudio digital ou do fluxo de áudio digital com a do fluxo de áudio analógico.
