Patent ID: 7738545

Claim:
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: p ⁡ ( t ) = ∑ n = 0 M - 1 ⁢ ⁢ w ⁡ [ n ] ⁢ g ⁡ ( t - n ⁢ ⁢ T 0 ) , where w[n] represents the n th tap coefficient, T 0 represents the spacing of the coefficients, M represents the number of tap coefficients, g(t) represents analog pulse shaping, and p(t) represents the digitally filtered UWB pulses.
