EFFECT: low average noise power in the output mixture of a matched filter with insignificant reduction of the peak value of the signal, which leads to additional increase in the signal to noise ratio at the same signal energy and spectral density of noise power at the filter input.;2 cl, ...
It also returns the noise vector 'n' that is added to the signal 's' and the power spectral density N0 of noise added Parameters: s : input/transmitted signal vector SNRdB : desired signal to noise ratio (expressed in dB) for the received signal L : oversampling factor (applicable...
Hence, the MBA model hypothesizes that the internal neural noise and external white noise work additively based on the stochastic resonance concept. Stochastic Resonance (SR) is a phenomenon in which signal processing is improved by adding random noise (e.g., white noise). In other words, ...
This MATLAB function calculates the Detection SNR Threshold in decibels for detecting a deterministic signal in white Gaussian noise.
Y= awgn(X,snr)adds white Gaussian noise to the vector signalX. This syntax assumes that the power ofXis 0 dBW. For more information about additive white Gaussian noise, seeWhat is AWGN? Y= awgn(X,snr,signalpower)accepts an input signal power value in dBW. To measure the power ofXbefor...
In Chapter 2, we develop a simple signal processing technique that can reduce additive Gaussian noise in some situations. Since noise is random, a time function or time plot is not particularly useful. It is more common to discuss other properties of noise such as its probability distribution,...

The present invention discloses a method for detecting silence by the white noise of the speech signal, comprising the steps of: treating stream digital voice signal processing is performed first sub-frame processing to obtain the first sub-frame signal; first sub-frame frequency domain signal ...
Add AWGN to Sawtooth Signal Create a sawtooth wave. t = (0:0.1:60)'; x = sawtooth(t); Add white Gaussian noise and plot the results. y = awgn(x,10,'measured'); plot(t,[x y]) legend('Original Signal','Signal with AWGN') Estimate Symbol Rate for General QAM Modulation in AWG...
