Some specific problems of ultrawideband wireless systems
Ďurovič, Svetozár
The paper is devoted to some selected problems, specific for the ultrawideband technology. First at all we are introducing the work of ITU-R on harmonising the new technology with the existing radiocommunication systems. The we deal with power utilisation of the various PDS masks and with the existence of discrete spectral components in emitteed signals. The report try to collect contemporary state of art and comment the situation by implementation UWB systems.
