I am confused about how to give the expression of noise. Can someone tell me if my equations are correct?
If the received RF signal is expressed as:
If I want to add a AWGN, can I give the expression of noise as the following?
If not, what is the correct equation of the noise? Also, in the MATLAB simulation, I often add noise to a baseband signal by using: sqrt(NoisePower) * randn(). What should I do in the case of bandpass signal? Thanks guys!
