Abstract

LA INVENCION SE REFIERE A UN RECEPTOR Y A UN METODO DE TRANSMISION DE DATOS EN UN SISTEMA EN EL QUE SE UTILIZA UN METODO DE ACCESO MULTIPLE CDMA Y EN DONDE CADA SEÑAL DE DATOS (30) A TRANSMITIR SE MULTIPLICA POR UN CODIGO PSEUDOALEATORIO (40) DE UNA CIERTA LONGITUD, QUE TIENE UNA VELOCIDAD DE BITS QUE ES MAYOR QUE LA DE LA SEÑAL DE DATOS A TRANSMITIR. PARA ASEGURAR UNA RECEPCION RAPIDA Y BARATA, LA SEÑAL MULTIPLICADA POR EL CODIGO PSEUDOALEATORIO SE MODULA ADICIONALMENTE EN UN METODO DE ACUERDO CON LA INVENCION MEDIANTE UN GRUPO DE FORMAS DE ONDA (F{SUB, 1).. F{SUB, N}) CUYO NUMERO IGUALA AL NUMERO DE BITS EN EL CODIGO PSEUDOALEATORIO, LA FRECUENCIA DE CADA FORMA DE ONDA ESTA INCLUIDA EN EL DOMINANTE DE FRECUENCIAS DADO. DE ACUERDO CON EL METODO, LA SEÑAL SE CONVIERTE EN EL RECEPTOR A UNA FORMA DIGITAL Y SE MULTIPLICA POR EL CODIGO PSEUDOALEATORIO QUE HA SIDO EXPUESTO A UNA TRANSFORMACION INVERSA DE FOURIER, Y LA SEÑAL MULTIPLICADA SE EXPONE A UNA TRANSFORMACION DE FOURIER.
