Abstract

"DETERMINAçãO DO CONTROLE DE POTêNCIA DE ENCAMINHAMENTO NOS SISTEMAS DE COMUNICAçãO DE ESPECTRO AMPLO". Um sistema de comunicação de espectro amplo onde o controle de potência mitiga as flutuações do sinal recebido é descrito. Uma implementação para o controle da potência de encaminhamento em que os dados recebidos são verificados quanto a erros, é descrita. Quando um erro é detectado, são determinados os níveis de energia dos bits de controle de potência e dos bits de tráfego. Os níveis de energia dos bits de controle de potência são comparados contra um primeiro limite predeterminado (105) em que se o nível de energia dos bits de controle de potência for inferior ao primeiro limite predeterminado, um aumento na potência de encaminhamento é solicitado (106). Caso contrário, os níveis de energia dos bits de tráfego são comparados contra um segundo limite predeterminado (107) em que se o nível de energia dos bits de tráfego for inferior ao segundo limite predeterminado, é solicitada uma diminuição na potência de encaminhamento. Caso contrário, é solicitado um aumento (108).
