The CDM‐750 CnC module operates on the near‐zero signal before the demodulator, and is
waveform agnostic. This means that no prior knowledge of the underlying modulation, FEC, or
any other waveform specific parameter is required in order to perform the signal cancellation
operation. The only caveat to this is that the waveform must be sufficiently random.
