How to generate AWGN noise in matlab?
The function y = awgn(x,SNR, measured ), first measures the power of the signal vector x and then adds white Gaussian Noise to x for the given SNR level in dB. The resulting signal y is guaranteed to have the specified SNR.
Why AWGN are added?
Additive white Gaussian noise (AWGN) is a basic noise model used in information theory to mimic the effect of many random processes that occur in nature. The modifiers denote specific characteristics: Additive because it is added to any noise that might be intrinsic to the information system.
Which Simulink block is used for adding white noise in a modulated communication system?
The AWGN Channel block adds white Gaussian noise to the input signal. It inherits the sample time from the input signal.
