Abstract

Un transmisor en una red inal?mbrica transmite conjuntamente el indicador de calidad de canal (CQI) y el reconocimiento de paquete de datos (Ack) o solo CQI dentro del mismo subcuadro sin la transmisi?n de datos de enlace ascendente que puede ser f?cilmente detectada en un receptor; cuando es apropiado un prefijo c?clico (CP) corto, un primer enfoque utiliza una se?alizaci?n auxiliada por piloto utilizando dos cubiertas Walsh diferentes para los pilotos a fin de se?alizar CQI contra CQI+ACK; cuando un CP largo es apropiado con un piloto, se proporcionan dos dise?os de c?digo diferentes para CQI y CQI+ACK que ?nicamente optimizan el libro de c?digos para cada modo separadamente, pero tambi?n maximizan la distancia entre estos dos espacios de c?digo; diversos enfoques basados en clases de grupos se describen para buscar dichos c?digos de bloque lineal; los resultados iniciales mostraron que se pueden encontrar buenos c?digos con base en el enfoque basado en clase de grupo para reducir al m?nimo la falsa alarma y la mala detecci?n.
