Document Type and Number:
WIPO Patent Application WO/2011/078498
Kind Code:
A2
Abstract:
The present invention relates to a multiple-mode broadband wireless communication device and method, wherein a multiple-mode broadband sending device comprises: a baseband output unit which outputs a plurality of digital signals in parallel; an intermediate frequency processing unit which subjects the digital signals, which have been output in parallel, to up-conversion to intermediate frequencies in a range in which they do not interfere with each other; a conversion unit which converts the parallel digital signals, which result from the up-conversion to the intermediate frequencies, to series digital signals; a digital-analogue conversion unit which converts the series digital signals to analogue signals; and a wireless frequency processing unit which converts the analogue signals to a transmission frequency corresponding to the required communication service.
