Abstract

LA INVENCION SE REFIERE A UN RECEPTOR DE ESTACION DE BASE Y UN METODO DE RECEPCION EN UN RADIOSISTEMA CELULAR CDMA QUE COMPRENDE EN CADA CELULA AL MENOS UNA ESTACION DE BASE (100) QUE SE COMUNICA ESTACIONES MOVILES (102-104) SITUADAS DENTRO DE SU AREA. LAS ESTACIONES DE BASE (100) MIDEN EL ANGULO DE DIRECCION DE UNA SEÑAL QUE LLEGA DE CADA ESTACIONES MOVILES (102-104) CON RESPECTO A LA ESTACION DE BASE, Y SE COMUNICAN CON LAS ESTACIONES MOVILES (102-104) USANDO HACES DE ANTENA QUE CAMBIAN EN EL TIEMPO, LOS ANGULOS DE MAYOR GANANCIA DE LOS HACES SON AJUSTADOS SEGUN LOS COMPONENTES DE SEÑAL (110-112) QUE LLEGAN DESDE LA ESTACION MOVIL. PARA SUMINISTRAR LA DETECCION DE BUENA CALIDAD SIN UNA GRAN CANTIDAD DE CALCULO, EN EL METODO SEGUN LA INVENCION LA DETECCION DE LA SEÑAL DESEADA UTILIZA SIMULTANEAMENTE VARIAS SEÑALES RECIBIDAS DESDE DIFERENTES ESTACIONES MOVILES, LA DIRECCION DE LLEGADA DE LAS SEÑALES ES TOMADA EN CUENTA CUANDO SE SELECCIONAN LAS SEÑALES.
