Nonparametric Estimation of the Phase Difference Using RV1 and MSL Windows

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