Frequency Estimation Using Analytic Signal via Wavelet Transform

Frequency estimation of a sinusoid in white noise using
maximum entropy power spectral estimation has been shown to be
very sensitive to initial sinusoidal phase. This paper presents use of
wavelet transform to find an analytic signal for frequency estimation
using maximum entropy method (MEM) and compared the results
with frequency estimation using analytic signal by Hilbert transform
method and frequency estimation using real data together with MEM.
The presented method shows the improved estimation precision and
antinoise performance.
