Abstract

Un método para detectar la calidad digital de una señal de radio incluye. Recibir una señal de radio que incluye una porción digital modulada por una serie de símbolos cada uno que incluye una pluralidad de muestras, computar puntos de correlación entre muestras de punto final en regiones de prefijo cíclico de símbolos adyacentes. Y usar los puntos de correlación para producir una métrica de calidad de señal digital. Se proporcionan también receptores que implementan el método.
