|Abstract: ||Described herein are various technologies relating to processing a
coherent signal. A receiver is configured to receive an analog signal,
and process the analog signal to generate an input analog signal. The
input analog signal has been modulated according to a suitable modulation
sequence. A coherent signal sampler coherently samples the modulation
sequence, and the result of such sampling is in turn used to demodulate
the input analog signal. The resultant signal is then passed to a sigma
delta modulator, where it is converted to digital form.
