METHOD AND APPARATUS FOR MULTI-MODE ULTRA BROADBAND WIRELESS COMMUNICATIONS

摘要

PURPOSE: A device for multiplex mode wide band wireless communication and method thereof are provided to process a plurality of digital signals transformed with a method requesting each communication service at once by mixing the signals at a range where the signals are not interfered to each other. CONSTITUTION: A baseband output unit(110) outputs a plurality of digital signals in parallel. An intermediate frequency processing unit(120) up-converts the outputted digital signal into a middle frequency at a range where the signals are not interfered to each other. A parallel-serial converter(130) changes the parallel digital signal, which is up-converted into a middle frequency, into a serial digital signal. A digital-to-analog conversion unit(140) changes the serial digital signal into an analog signal. A radio frequency process unit(150) changes the analog signal into a transmission frequency corresponding to the required communications service.
