description The system and method characterize a communications channel with respect to signal-to-noise ratio (SNR), time dispersion or multi-path, and frequency dispersion or Doppler spread. A probe signal demodulator receives a probe signal transmitted on a wireless communication channel and generates a demodulated probe signal, and a probe signal re-modulator generates a replica probe signal. A delay unit generates a delayed probe signal, and an adaptive canceller receives the delayed probe signal and the replica probe signal, and generates a residual noise signal and a channel characterization signal. A channel characterization block receives the channel characterization signal and the residual noise signal to generate channel measurements of the wireless communication channel.
