Abstract
In this letter, we present a new method for estimating the number of harmonics in colored noise using enhanced matrix. We construct an enhanced matrix from the data samples and then analyze the eigenvalues of the covariance matrix of enhanced matrix. The number of harmonics is inherent with the eigenvalues, and it can be estimated using the special property of the eigenvalues. The presented method does not assume the distribution and color of the additive noise. Simulation results are provided to verify the effectiveness of the presented method
