Abstract

Para un esquema de canal iterativo y estimacion de interferencia y descodificacion, se obtiene inicialmente informacion anterior para interferencia y ganancia de canal sobre la base de símbolos de piloto recibidos. La informacion directa para los bits de codigo correspondientes a los símbolos de los datos recibidos se deriva sobre la base de los símbolos de los datos recibidos y de la informacion previa, y luego se descodifican para obtener informacion de realimentacion para los bits de codigo correspondientes a los símbolos de los datos recibidos. Una informacion a posteriori para cada uno de los símbolos de los datos recibidos y la informacion previa se combinan para obtener la informacion actualizada para interferencia y ganancia de canal para cada uno de los símbolos de datos recibido. El proceso se puede repetir para cualquier cantidad de iteraciones. La informacion previa, la informacion a posteriori, y la informacion actualizada se pueden representar con distribuciones de probabilidad conjunta sobre interferencia y ganancia de canal. La informacion previa y de realimentacion se puede representar a través de relaciones símil registro (LLRs).
