Abstract
"APARELHO E PROCESSO PARA MELHORAR A FAIXA DINâMICA DE UM RECEPTOR, E, SISTEMA PARA RECEBER E TRANSMITIR SINAIS". Um aparelho, sistema e processo melhoram a faixa dinâmica de um receptor na presença de um sinal de interferência de faixa estreita. Uma taxa de erro de um sinal recebido é computada, e o ponto de interceptação de entrada de um amplificador de baixo ruído no receptor é ajustado, baseado na taxa de erro. O nível de potência de transmissão é detectado, e o ponto de interceptação de entrada é ajustado baseado também no nível de potência de transmissão. A força de sinal recebido é também detectada, e o ganho do amplificador de baixo ruído é ajustado baseado na força de sinal recebido. Desta maneira, o efeito de modulação cruzada no sinal recebido é reduzido.
