How do you add noise to a simulation?

To include noise in the simulation, you must select the Add noise check box on the Input Port block dialog box. This check box is selected by default. For information on how the blockset simulates noise, see Model Noise in an RF System.

How to add noise to data matlab?

y = awgn( x , snr ) adds white Gaussian noise to the vector signal x . This syntax assumes that the power of x is 0 dBW. For more information about additive white Gaussian noise, see What is AWGN? y = awgn( x , snr , signalpower ) accepts an input signal power value in dBW.
