Abstract
A frequency synthesizer in an ultra wide band (UWB) wireless communication system which transmits and receives data through multiband includes a frequency generation means which generates a plurality of frequency signals; and a frequency adjustment means which receives the plurality of frequency signals from the frequency generation means and generates center frequencies of all or part of sub-bands within the UWB through the frequency adjustment. Since all of the center frequencies of the sub-bands are generated, the utilization of the sub-bands can be enhanced for the wideband wireless communication. Furthermore, it is possible to enable the stable UWB communications by flexibly utilizing all of fourteen sub-bands since the sub-bands suffer less from the frequency interference in a complicated and variable wireless frequency environment.
