Abstract
Un control de ganancia automático de receptor incluye un receptor de ganancia variable (304, 308, 312) que tiene una entrada de control y es sensible a unasenal de control de ganancia para ajustar el nivel de salida del receptor. Un controlador(114) está acoplado al receptor de ganancia variable. El controladormonitorea una calidad de senal recibida y un nivel de potencia de senal recibido. El controlador genera una senal de control para controlar la gananciavariable en funcion de lacalidad de senal y el nivel de potencia, El controlador controla la ganancia en funcion del nivel de potencia recibido y controlaselectivamente la ganancia en funcion de la calidad de senal.
