Abstract
This paper presents a new harmonics frequency estimation method. Unlike the conventional harmonic frequency
estimation method (fast Fourier transform), the new algorithm is based on spectrum analysis techniques often used to
estimate the direction of angle; the most popular is the multiple signal classification (MUSIC) algorithm. The drawbacks
of MUSIC algorithm are concluded. Improved-MUSIC approximation algorithm is introduced and compared with FFT
based on algorithm for harmonic frequency estimation. Theoretical analysis and simulations show this algorithm is a super-
resolution algorithm with small data length.
