Abstract

Métodos mejorados para estimación de calidad de canal utilizan datos de salida de símbolo soft para generar una estadística o conjunto de estadísticas que son representativas de la BER para cada una de una pluralidad de ráfagas correspondientes a un canal compuesto. Las estadísticas son mapeadas en un estimado de BER para generar estimados e BER individuales para cada una de la pluralidad de ráfagas. Los estimados de BER individuales son combinados para obtener un estimado de la BER para todo el canal compuesto. En forma alternativa, el estimado de BER para el canal compuesto puede luego ser mapeado en un estimado de calidad para el canal compuesto utilizando una función monotónica.
