Abstract

This paper describes the measurement and nonparametric estimation of phase difference with stronger inhibition of spectral leakage. The phase difference is estimated by discrete Fourier transform coefficients around component peaks using Rife-Vincent windows class I (RV1) and the minimum side-lobe level (MSL) windows. Selecting a suitable window order, MSL windows demonstrate a very low bias error and lower noise error propagation than RV1 windows. A practical example evaluates the accuracy of the used windows in estimations.
