1. A method of demodulating an ultra-wideband communication signal, the method comprising the steps of:
- receiving an incoming signal, wherein the incoming signal comprises a plurality of ultra-wideband pulses;
approximating the incoming signal;
generating a local signal;
generating a first output signal and a second output signal;
quantizing the first output signal and the second output signal to produce a first quantized signal and a second quantized signal;
generating a difference signal for the first quantized signal and the second quantized signal; and
providing an error signal based on the difference signal.
