A frequency estimator based on the linear prediction property of sinusoidal signals has recently been proposed for the direct estimation of real tone frequency in white noise. We propose a variable step-size direct frequency estimator (VS-DFE), which shows improved performance on account of the use of a dynamically updated step-size instead of a fixed step-size. A comparison of the simulation results of the proposed estimator with those of conventional estimators clearly indicates its superior performance.
