Abstract: Un procedimiento (700) de comunicación, que comprende: obtener (712) datos recibidos para una transmisión de múltiples entradas y múltiples salidas, MIMO; procesar (714) los datos recibidos en base a un filtro de sección de entrada (410) para obtener datos filtrados; procesar (716) los datos filtrados en base a, al menos, una primera matriz de combinación para obtener datos detectados para una primera trama, en el que una matriz de combinación combina componentes de señal temporizadas en los datos filtrados para un código de canalización para obtener datos detectados para el código de canalización, en el que las componentes de señal temporizadas son componentes de señal que hacen referencia a un símbolo deseado que va a ser recuperado, así como a otros símbolos transmitidos al mismo tiempo que el símbolo deseado; procesar (718) los datos detectados para la primera trama para obtener datos descodificados para la primera trama; determinar si la primera trama está descodificada correctamente; y procesar (720) los datos filtrados en base a, al menos, una segunda matriz de combinación y datos descodificados para la primera trama cuando la primera trama está descodificada correctamente para cancelar interferencia debida a la primera trama y obtener datos detectados para una segunda trama; y en el que el procesamiento de los datos filtrados en base a la al menos una segunda matriz de combinación comprende estimar la interferencia solamente debida a las componentes de señal temporizadas de la primera trama, y cancelar la interferencia de los datos filtrados.

Abstract: Techniques for receiving a MIMO transmission are described. A receiver processes received data for the MIMO transmission based on a front-end filter to obtain filtered data. The receiver further processes the filtered data based on at least one first combiner matrix to obtain detected data for a first frame. The receiver demodulates and decodes this detected data to obtain decoded data for the first frame. The receiver then processes the filtered data based on at least one second combiner matrix and the decoded data for the first frame to cancel interference due to the first frame and obtain detected data for a second frame. The receiver processes this detected data to obtain decoded data for the second frame. The front-end filter processes non on-time signal components in the received data. Each combiner matrix combines on-time signal components in the filtered data to obtain detected data for a channelization code.
