  Compared to narrowband RF and spread spectrum, UWB uses extremely wide
bandwidth, if the emission power is not well controlled, UWB devices might cause
interference with other existing systems.

  Gaussian derivative provide excellent radiation properties
  As the order of the derivative increases, the energy is
moving to higher frequencies
  Higher order Gaussian derivative do not need frequency
shift to fit the FCC mask, but not in a power efficient manner

  Pulse position modulation (PPM) where each pulse is
delayed or sent in advance of a regular time scale.
  Bi-phase modulation create a pulse with opposite
phase.
  Orthogonal Pulse Modulation, which requires special
pulse shapes to be generated that are orthogonal to each
other.
