ABSTRACT:
A signal to be transmitted is modified. An ultra wideband (UWB) signal to be transmitted is obtained, the UWB signal having a data carrying sub-band and a non data carrying sub-band. Information in the non data carrying sub-band is modified so that the power associated with the non data carrying sub-band is less than the power prior to the modification. Information in the data carrying sub-band is modified so that the power associated with the data carrying sub-band is greater than the power prior to the modification. The amount by which the data carrying sub-band increases in power is based at least in part on the amount by which the non data carrying sub-band decreases in power. A UWB signal is transmitted having the modified information in the non data carrying sub-band and the modified information in the data carrying sub-band.
