Abstract
LA PRESENTE INVENCION SE REFIERE A UN METODO Y UN APARATO PARA RECIBIR CONVERTIR SEÑALES DE ESPECTRO EXTENDIDAS. DICHOS METODOS Y DICHO APARATO PERMITEN RECIBIR SEÑALES DE ESPECTRO EXTENDIDA EN BANDAS DE FRECUENCIA DIFERENTES SUSTANCIALMENTE SIMULTANEAS EN LA MISMA CADENA DE COMPONENTES DE HARDWARE. LAS SEÑALES RECIBIDAS SON PROCESADAS EN LA MENCIONADA CADENA DE COMPONENTES DE HARDWARE Y LA SEÑAL RESULTANTE DE ESTA PUEDE SER UTILIZADA, A CONTINUACION, DENTRO DE UN CIRCUITO ELECTRONICO. EL MENCIONADO METODO SE COMPONE DEL PASO DE CONVERSION DE SEÑALES ANALOGICAS EN UNA SEÑAL DIGITAL DE MENOR FRECUENCIA. DICHO PASO DE CONVERSION CONSTA DE LOS PASOS DE CAPTURA DE UNA PLURALIDAD DE SEÑALES DE ENTRADA DENTRO DE UNA GAMA ESPECTRAL PREDETERMINADA, QUE ELIMINA DE LAS MENCIONADAS SEÑALES DE ENTRADA UNA PRIMERA PLURALIDAD DE SEÑALES DE AMPLIO ESPECTRO ANALOGICAS EN UNA PLURALIDAD DE BANDAS PREDETERMINADAS CON ANCHOS PREDETERMINADOS, Y EL MUESTREO DE LAS MENCIONADAS SEÑALES ANALOGICAS CON UNA FRECUENCIA DE MUESTREO FS DONDE FS ES ELEGIDA DE FORMA QUE LA SEÑAL DE TIEMPO DIFERENCIADO RESULTANTE CONSTA DE UNA SEGUNDA PLURALIDAD DE SEÑALES DE ESPECTRO DE AMPLITUD ANALOGICA, Y LA MENCIONADA PRIMERA PLURALIDAD DE SEÑALES DE AMPLIO ESPECTRO ANALOGICAS CON ALIASING SIN AUTOALIASING SUSTANCIAL.
