Abstract

Se describe un metodo para ajustar de manera optima el umbral de deteccion de bits recibidos en un sistema de comunicacion digital, tal como un sistema de TDMA que esta caracterizado por transmisiones de rafaga de duracion muy corta; en una modalidad de la invencion, se utiliza un modem de radio semiduplex para transmision y recepcion de mensajes para servicio de Transmision de Vigilancia Dependiente Automatica (ADS-B) aerea y terrestre; se provee una trayectoria de retroalimentacion en la unidad de transmision/receptora para proveer la senal de transmision a la trayectoria receptora; un circuito de ajuste de umbral de deteccion de bits recibe la senal de transmision; el circuito digitaliza la senal de banda base analoga, detecta los valores pico positivo y negativo y calcula un valor de desviacion de pico a pico para definir el valor de umbral de deteccion de bits.
