Adaptive Window Zero-Crossing-Based Instantaneous Frequency Estimation

Adaptive Window Zero-Crossing-Based Instantaneous Frequency Estimation

<p/> <p>We address the problem of estimating instantaneous frequency (IF) of a real-valued constant amplitude time-varying sinusoid. Estimation of polynomial IF is formulated using the zero-crossings of the signal. We propose an algorithm to estimate nonpolynomial IF by <it>local&l...
