How do I add a AWGN noise to my signal?
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.
What happens if noise is added to a signal?
Noise is an unwanted signal which interferes with the original message signal and corrupts the parameters of the message signal. This alteration in the communication process, leads to the message getting altered. It is most likely to be entered at the channel or the receiver.
What is the power of AWGN?
AWGN Power
I oc is defined in C. S0033 as the power spectral density of a band-limited white noise source (simulating interference from other cells) as measured at the access terminal antenna connector. If you have accounted for path loss, then AWGN power is equivalent to I oc .
