Frequency Estimation Using Analytic Signal via Wavelet Transform
Abstract:
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.
Keywords:
Frequency estimation, analytic signal, maximum entropy method, wavelet transform.
