Pilot-Symbol-Assisted Phase Noise Compensation With Forward–Backward Wiener Smoothing Filters

We present a novel Wiener smoothing filter procedure for pilot-symbol-assisted estimation of oscillator phase noise. The procedure consists of forward and backward first-order infinite impulse response filtering the pilot symbols and combining the filter outputs to generate an estimate of the phase...
