Abstract

Un método de codificación en bloque y un sistema para la mejora de confiabilidad de la información de los Indicadores de Canal de Calidad (CQI) y los Indicadores de Ponderación de Antena (AWI). Una terminal de usuario en primer lugar genera CQI de 8 bits y AWI de 2 bits. Un generador de palabra de código produce una palabra de código que responde a estos 1 bits CQI/AWI utilizando un libro de código o una matriz generadora de un código (20, 10, 6) tiene una distancia Hamming mínima de 6. La palabra codificada es transmitida a un receptor para la decodificación utilización un libro de código (20, 10, 6) idéntico.
