Abstract

"APARELHO EM UM RECEPTOR EM UM SISTEMA DE COMUNICAçãO, PROCESSO DE PROCESSAMENTO DE SINAIS RECEBIDOS NA ESTAçãO BASE EM UM SISTEMA DE RáDIO TELEFONE CELULAR, E, SISTEMA DE COMUNICAçãO". Um aparelho para uso em um receptor em um sistema de comunicação no qual os sinais cobrem uma ampla faixa de níveis de energia. O aparelho fornece um consumo de energia reduzido sem sacrificar a sensibilidade do receptor pela utilização de um amplificador possuindo uma faixa dinâmica relativamente estreita e fixa que pode ser seletivamente posicionado para acomodar uma faixa ampla de níveis de energia. O amplificador é localizado mais cedo na corrente de processamento de sinal de receptor do que os amplificadores comparáveis nos receptores convencionais.
