Abstract

Un metodo y sistema para ajustar las caracteristicas de amplitud y fase de senales de comunicacion inalambrica generadas por un transmisor de radio analogo, en base a senales de control de potencia de transmision (TPC) recibidas por una estacion base (BS) y caracteristicas conocidas de un amplificador de potencia (PA) incluido en el transmisor. Un modulo de compensacion digital pre-distorsion, que tiene vias de senal real e imaginaria, recibe y procesa componentes de senal real e imaginaria utilizados para generar la senal de comunicacion inalambrica. Las caracteristicas de fase y amplitud de la senal de comunicacion inalambrica son controladas en respuesta a las senales TPC, de manera de corregir las caracteristicas de amplitud y fase alteradas del PA.
