MATLAB添加高斯噪声awgn函数(需要wgn函数) function y=awgn(varargin) %AWGN Add white Gaussian noise to a signal. % Y = AWGN(X,SNR) adds white Gaussian noise to X. The SNR is in dB. % The power of X is assumed to be 0 dBW.
Signal-to-noise ratio in dB, specified as: a scalar if the input signal is a scalar or a vector. a scalar or a vector if the input signal is a 3D array. For more information see, Array Support. The function applies the same snr value to each channel. The columns of the input sign...
MATLAB Online에서 열기 Theawgnfunction is implemented as a MATLAB function file in Communications Toolbox. If you have this toolbox installed, you can see the source code for this function. You can calltypeto display it in the Command Window (which could display a lot of text in the...
