Abstract:
1. A method comprising generating digitally filtered ultra-wide band (UWB) pulses to substantially maximize power in one or more frequency bands of a UWB spectrum and to substantially reduce power in one or more narrow band interference (NBI) frequency bands of the UWB spectrum, wherein generating the digitally filtered UWB pulses comprises: generating a stream of information bearing symbols; selecting spacing of a set of tap coefficients of a digital filter, the digital filter being included within a UWB transmitter; selecting the set of tap coefficients based on the one or more frequency bands; digitally filtering the stream of information bearing symbols according to the set of selected tap coefficients; and generating, by the UWB transmitter, the digitally filtered UWB pulses based on the following equation: where w[n] represents the n
