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 UWB bi-phase signal having a first arranged pattern;

    a mixer for combining the UWB bi-phase signals with an incoming 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 bi-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 bi-phase wavelets, wherein the first set of bi-phase wavelets and the third set of bi-phase wavelets are the same in wave shape and polarity, and wherein the second set of bi-phase wavelets and the fourth set of bi-phase wavelets are the same in wave shape, but are inverted in polarity.
