Abstract

Se describen un metodo y aparato para un dispositivo de comunicacion inalambrico para recibir simultaneamente por lo menos dos senales. Se proveen dos porciones receptoras en el dispositivo de comunicacion inalambrico; una primera porcion receptora esta configurada para recibir una primera senal de comunicacion. Una segunda porcion receptora esta configurada para recibir una segunda senal de comunicacion. Las dos porciones receptoras estan configuradas para convertir la primera y segunda senales de comunicacion en una banda de frecuencia comun; la banda de frecuencia comun puede ser una banda de frecuencia intermedia o banda de frecuencia de banda base; la primera y segunda senales de comunicacion convertidas se combinan en la banda de frecuencia comun utilizando una sumadora u otro combinador de senales; la senal combinada es procesada en un procesador de una sola senal; el dispositivo de comunicacion tiene la capacidad de resolver cada una de las senales recibidas cuando la primera senal de comunicacion es una senal de banda angosta y la segunda senal de comunicacion es una senal de banda ancha, tal como una senal de espectro disperso; el aparato se puede utilizar por ejemplo durante la transferencia entre celdas GSM y WCDMA.
