Abstract

Técnicas para procesar una cantidad de corrientes "recibidas" de símbolos en un sistema MIMO (múltiple input múltiple output, múltiples entradas, múltiples salidas), de manera tal que es posible lograr una performance mejorada cuando se utiliza el procesamiento SIC (succesive interference cancellation, cancelación sucesiva de las interferencias). En uno de los aspectos, se proveen métricas indicativas de la calidad o "bondad" de una corriente "detectada" de símbolos. Dichas métricas tienen en cuenta la respuesta frecuencia-selectiva de los canales de múltiples trayectorias utilizados para transmitir la corriente de símbolos. Por ejemplo, las métricas pueden referirse a: (1) una capacidad global de los canales para todos los canales de transmisión utilizados para la corriente de símbolos, o : (2) una relación SRN (relación entre senal, ruido o interferencia), equivalente, de un canal AWGN (de Ruido Blanco Gaussiano Aditivo) que modela dichos canales de transmisión. En otro aspecto se proveen técnicas para procesar las corrientes de símbolos recibidas, mediante el procesamiento SIC, a efectos de recuperar una cantidad de corrientes de símbolos transmitidas. El orden particular en el cual las corrientes de símbolos son recuperadas, es determinado en base a la métrica determinada para las corrientes de símbolos detectadas en cada una de las etapas de procesamiento de SIC.
