Abstract

Un método y un arreglo para el cálculo de calidad cuando se detecta un bloque de información, por ejemplo un bloque de información de voz transmitido en un sistema de radio comunicación de conformidad con el acceso múltiple de división de tiempo (TDMA), aunque el método también puede aplicarse con sistemas de radio por división de frecuencia. Se utiliza una información suave disponible en el radio receptor (RM, DM, DI, KD) que está destinada a detectar el bloque de información de voz y procesar esta información de señal de conformidad con aquellos principios aplicables a las redes neurales conocidas. Antes del uso, la red neural (NT) se alinea al sistema de radio comunicación concerniente. La invención permite una mejor información que se relaciona al error posible en el bloque de información de voz que va a entregarse a las unidades correctoras de error (TD) en el radio receptor.
