PREDICTIVE DIGITAL FILTERING OF SINUSOIDAL SIGNALS

p-step ahead predictive filters for narrowband waveforms with rr, dist inct spectral peaks are considered, By minimization of the noise gain, the coefficients of the optimal Lth order FIR predictor is derived, w here L > 2m -1, The minimum-length FIR predictor is given by L = 2m -1 , and the feedback extension of this predictor is studied. Design of f eedback gains subject to different optimization criteria is studied in detail, The generalization to complex-valued signals, cascaded predic tors, and adaptive predictors are also included, Several design and si mulation examples are presented.
