Abstract:
1. A self-noise cancellation mechanism for reducing performance degradation as a result of self-generated noise, comprising: a pulse-forming network for producing an internally-generated ultrawide bandwidth (UWB) bi-phase signal having a first arranged pattern; a mixer for combining the UWB bi-phase signal with an incoming Radio Frequency (RF) UWB signal having a second set pattern; and an integrator for accumulating an output of the mixer, wherein the first arranged pattern comprises a first set of hi-phase wavelets and an adjacent second set of bi-phase wavelets, wherein the second arranged pattern comprises a third set of bi-phase wavelets and an adjacent fourth set of hi-phase wavelets, wherein the first set of bi-phase wavelets and the third set of hi-phase wavelets are the same in wave shape and polarity, and wherein the second set of hi-phase wavelets and the fourth set of hi-phase wavelets are the same in wave shape, hut are inverted in polarity.
