Abstract
Un sistema (100) de comunicacion que incluye un circuito (105) de control automatico (AGC), un receptor (110), un conversor (115) de analogo a digital (ADC) y un modulo (120) de compensacion de variacion de fase de insercion. Circuito (105) AGC recibe y amplifica senales (150) de comunicacion. La ganancia del circuito (105) AGC es ajustada continuamente. Circuito (105) AGC da salida a una senal amplificada al receptor (110) que, a su vez, da salida a una senal compleja analoga al ADC (115). ADC (115) da salida a una senal compleja digital a un modulo (120) de compensacion de variacion de fase de insercion que contrarresta los efectos de desplazamientos de fase introducidos en la senal (150) de comunicacion debido a los continuos ajustes de ganancia asociados con el circuito (105) AGC.
