Abstract:
1. A method for modifying a signal to be transmitted, comprising: obtaining an ultra wideband (UWB) signal to be transmitted having a data carrying sub-band and a non data carrying sub-band; using a processor to modify information in the non data carrying sub-band so that the power associated with the non data carrying sub-band is less than the power prior to the modification; using a processor to modify information in the data carrying sub-band so that the power associated with the data carrying sub-band is greater than the power prior to the modification, wherein 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; and transmitting a UWB signal having the modified information in the non data carrying sub-band and the modified information in the data carrying sub-band.
