Abstract

La invencion se refiere a un metodo de procesamiento de senales que se utiliza en un dispositivo terminal de un sistema de comunicacion movil de acceso multiple por division de codigo; el metodo es una combinacion de diversidad de tiempo y deteccion de union para elevar la ganancia de diversidad del receptor; el metodo incluye los pasos de: hacer un muestreo multiple para la senal recibida en un dominio de tiempo; estimar la respuesta de canal espacial; obtener matrices; constituir una matriz de sistema; realizar un algoritmo de deteccion de union, obtener un calculo de los datos de transmision originales; cuando el metodo se utiliza en una terminal movil, se puede resolver el problema de desbalance entre el desempeno de enlace ascendente y enlace descendente para que se pueda volver a usar la frecuencia, y que se pueda utilizar la deteccion de union relativamente facil; el metodo tambien se podria aplicar en la estacion base.
