To improve the write performance of PCM, this paper proposes a new write scheme, called
two-stage-write, which leverages the speed and power difference between writing a zero bit …

A frequency estimator of sinusoid based on interpolation of three discrete Fourier transform
(DFT) spectral lines is proposed. The FFT is performed first on the sampled sinusoid signal …

Polygonal wear of railway wheels will accelerate the failure of critical structure. It is of great
significance to monitor their state in service. However, affected by the frequently changed …

An accurate frequency estimator of complex sinusoid in additive white noise is proposed. It
is based on interpolation of Fast Fourier Transform (FFT) and Discrete-Time Fourier …

Frequency estimation of a single complex exponential signal embedded in additive white
Gaussian noise is a major topic of research in many engineering areas. This work presents …

Interpolators are widely employed in the frequency estimation of sinusoidal signals.
However, for a real-valued sinusoidal signal, the existing interpolators do not consider the …

An accurate frequency estimator for real sinusoid based on Discrete Fourier Transform
