Abstract

Un método para actualizar una senal recibida compensa la selectividad de las frecuencias del canal de comunicaciones por el hecho de tomar en cuenta errores en la estimacion del canal. El método comprende generar estimaciones del canal para la senalrecibida, calcular ponderaciones de filtro para un ecualizador sobre la base de dichas estimaciones del canal y de una covarianza del error en la estimacion del canal, y filtrar la senal recibida mediante el uso de las ponderaciones de filtrocalculadas.
