original signal

The task of a phase-lock receiver is to reproduce the original signal while removing as much of the noise as possible.

Noise is understood as the inherent noise of a receiver, which reduces the original signal-to-noise ratio of an input signal.

EMD method is the key step of the process, "screen" by over the original signal, the screen each IMF component and trends.

Signals from the anti-Juanji Juanji blind separation of the original signal, signal can be used to reduce the seismic wavelet extraction.

The lowest frequency components of the IMF usually represent the original signal trend or value.

First, we use AR model to predispose original signal, distill the calculated AR coefficients as its eigenvector.

This paper describes the process from original signal transformation to display.

This creates extra harmonics that are not present in the original signal.

By decomposing original signal into simple oscillation modes empirically , we can obtain meaningful instantaneous frequencies.

Moreover, in order to recover the original signal efficiently, the frequency warping is implemented by Laguerre filter instead.

EEG signal always has a low signal noise ratio (SNR), because the original signal itself is faint and unstable.

Application of Wavelet Transform to Radar Original Signal Compression

Firstly, db4 wavelet reduction noise of original signal , which shows the testing is good;
