Abstract

Cuando un codificador realiza la multiplexion IQ de senales transferidas desde un propagador y un distribuidor con el fin de generar una senal compleja (senal I y senal Q), los coeficientes de amplitud 'cc (I) y 'cc (Q), se determinan de acuerdo con las potencias de la senal en el eje I y el eje Q.
