Abstract

Se revelan un método y un aparato para minimizar el retardo en el procesamiento incurrido por un receptor de IC por sobre receptores convencionales en un sistema celular de CDMA. El método y el aparato implican operar el receptor convencional y el receptor de IC en paralelo entre sí. Los datos del receptor convencional son luego usados para complementar a los datos desde el receptor de IC a fin de minimizar los retardos incurridos por el receptor de IC.
