Abstract
Se describen técnicas para llevar a cabo la deteccion de datos para una transmision de datos jerárquicamente codificada. En un esquema para la deteccion de los datos, se derivan inicialmente LLRs (relaciones de probabilidad logarítmica) para los bits de codigo de una primera corriente de datos sobre la base de símbolos recibidos para la transmision de los datos. Los LLRs para la primera corriente de datos se decodifican para obtener datos decodificados, que son recodificados y remodulados para obtener símbolos remodulados. La interferencia debida a la primera corriente de datos se estima sobre la base de los símbolos remodulados. Los LLRs para los bits de codigo de una segunda corriente de datos se derivan sobre la base de los LLRs para los bits de codigo de la primera corriente de datos y la interferencia estimida. Los LLRs para la primera corriente de datos pueden derivarse a partir de los símbolos recibidos en tiempo real sin poner los símbolos recibidos en memoria intermedia. Los LLRs para la segunda corriente de datos pueden derivarse después de haberse decodificado la primera corriente de datos.
