Abstract
Se describe una tecnología de compresión digital única para aumentar la capacidad que transporte información de una vía de trayectoria de comunicaciones limitada de ancho de banda al utilizar una técnica de codificación y modulación combinada. La tecnología inventiva permite que múltiples corrientes de datos moduladas independientes compartan simultánea e instantáneamente el mismo ancho de banda sin la interferencia de canal cruzado. Se utiliza un filtro coincidido para reducir substancialmente la velocidad de error y utiliza un método de entrenamiento único con base en la realización de una prueba de respuesta espectral. Un algoritmo calcula el efecto de las características únicas de la vía de comunicaciones sobre la señal transmitida y genera una señal ideal almacenada en el filtro coincidido para comparación con señales recibidas.
