Abstract
Un método para procesar una senal recibida al corregir un valor de la relacion Senal de Interferencia (SIR) de la no linealidad y un método para procesardicha senal como una funcion de su valor (SIR) medido. Usando estimaciones medidas de los valoresde energía de senal recibida y de interferencia, se determinaun valor de relacion senal a interferencia (SIR). El valor de SIR es corregido de la no linealidad para obtener un valor de SIR corregido usando una funcion decorreccion. Ese valor de SIRcorregido puede entonces ser usado en cualquier numero de aplicaciones tal como para controlar la potencia de transmision de los moviles en un sistema de radio comunicaciones moviles. La presente también propone una disposicion de comunicaciones de espectro disperso para llevar a lapráctica dicho método.
