Abstract

Un método en un terminal de comunicaciones móviles de acceso múltiple por división de códigos, que comprende la recepción de una primer senal en la terminal; la recepción de una segunda senal en la terminal, la primer senal es no ortogonal con respecto a la segunda senal; el aumento de la capacidad de enlace de envío de un sistema de comunicación de acceso múltiple por división de códigos del cual se reciben las primeras y las segundas senales no ortogonales cancelando una de las primeras y segundas senales en la porción de procesamiento de rastrillo del terminal. Un método en un sistema de comunicación de acceso múltiple por división de códigos que incluye una red de estación base y un método en un sistema de comunicación de acceso múltiple por división de código que comprende una infraestructura de red y una pluralidad de terminales móviles.
