Abstract

Un receptor de diversidades (300) ha manejado la estimación de una diversidad de parámetros de peso. El receptor recibe diferentes versiones de una señal (101) que tiene datos codificados, combina las versiones y decodifica los datos contenidos dentro de la combinación. La salida de los datos decodificados se recodifica luego usando una técnica similar como la de un transmisor que transmite la señal (101). Los datos recodificados se usan luego para calcular una diversidad de parámetros de peso que se usan para modificar una réplica almacenada de cada versión. Las versiones modificaciones se combinan luego y se decodifican para originar una estimación más precisa de la información contenida dentro de la señal (101) en un receptor de diversidades (300).
