ESTIMATION OF FREQUENCIES FROM MODIFIED LINEAR PREDICTION METHODS

The problem of estimating the frequencies of multiple sinusoids from noisy measurements by using the modified linear prediction methods - Modified Forward-Backward Linear Prediction(MFBLP) and Model Reduction(MR) methods is addressed in this paper. The MFBLP and MR methods are derived by singular value decomposition and approximation of linear system. respectively. Monte Carlo simulations are done and the performances compared with linear prediction and forward-backward linear prediction. Simulations show a great promise for MFBLP and MR.
