Abstract

"SISTEMA DE REALIMENTAçãO APERFEIçOADO UTILIZANDO DECODIFICAçãO DINâMICA". Métodos e equipamento são apresentados para decodificar dinamicamente os sinais de confirmação. Uma fonte recebe um sinal de confirmação (410) e inicia o monitoramento de um valor de energia associado com o sinal de confirmação (412) . Se o valor de energia exceder uma quantidade limite predeterminada antes do final do sinal de confirmação, então a fonte tem confiança que a parte do sinal de confirmação recebida até esse ponto pode ter sido decodificada com sucesso. Dessa forma, a fonte decodifica essa parte do sinal de confirmação (416) e desconsidera o restante do sinal de confirmação.
