4. The multi-differential frequency- shift receiver of claim 3, wherein the demodulator includes:
a mixer, multiplier or any square law device that squares the plurality of data signals and the common reference signal;
a plurality of additional mixers that frequency shift the squared signal; and
a plurality of integrators that integrate the frequency shifted signal to provide the demodulated data signal.
5. The multi-differential frequency-shift reference receiver of claim 1, wherein the MD-FSR receiver is for an ultra- wideband (UWB) radio.
