Abstract

Un metodo y aparato para proporcionar un estimado de la proporcion de senal a ruido (SNR) de enlace ascendente en un sistema de comunicacion inalambrica. Se recibe una primera senal a traves de un primer canal, y se recibe una segunda senal a traves de un segundo canal, en donde la segunda senal es recibida en un nivel de potencia de senal superior al de la primera senal. Se mide la proporcion de senal a ruido (SNR) de la segunda senal, y se determina la SNR de la primera senal, con base al menos en parte, en la SNR medida de la segunda senal.
