Abstract

Un método para seleccionar una matriz de precodificacion que se utilizará en un sistema de comunicacion de MIMO (100) que comprende un transmisor (105), un receptor (115) y un canal de comunicacion (110), en el cual la matriz de precodificacion es utilizada por el transmisor para precodificar palabras en clave que se transmitirán al receptor por el canal de comunicacion. En el receptor, se determina una matriz optima de precodificacion dentro de un manual de codigos de matrices de precodificacion sobre la base de una métrica relacionada con la potencia de las capas de senal recibida. Luego se reingresa una indicacion desde el receptor hacia el transmisor util para habilitar al transmisor para que seleccione la matriz optima de precodificacion del manual de codigos.
