Abstract

Procedimiento para la medición de las propiedades de canales de radio, en el que las señales de recepción son recibidas por un número (M1) de sensores de recepción (S1-SM) de un grupo de antenas lineales (ULA), donde las señales de recepción respectivas están compuestas por ondas parciales de una señal de emisión de diferente dirección de incidencia y de diferente retraso, caracterizado porque la señal de emisión contiene una secuencia de prueba previamente seleccionada, las señales de recepción son demoduladas y a continuación se lleva a cabo un muestreo, se alimentan valores de muestreo que resultan durante un cálculo de vectores propios, que corresponden con valores propios dominantes, siendo derivada una matriz del espacio inferior de la señal a partir de los vectores propios calculados, se establecen ecuaciones de invarianza que dependen de la matriz del espacio inferior de la señal, los valores estimados para el ángulo de incidencia y los retrasos de frentes de ondas dominantes son determinados por medio de la resolución de las ecuaciones de invarianza.
