Add noise to multi-signals
3 views (last 30 days)
I want to simulate a received signal which has three sins-wave signals at different frequencies with difference amplitudes and phases, say: (f(i), a(i), p(i)), i=1,2,3. The receiver has certain noise. The Rx noise compares with the received signal powers, we have SNR(i).
How do I model this signal in time-domain?

%Change the paramerts as per requirements
noise=noiseAmplitude* rand(1, length(t));
