DEAR ALL:
Iwant to simulate a RF system, the question is how can I generate a noise with a required sensitivily power ? i.e. -174 dBm. Please help me, thanks

First: calculate the power value.
-174dBm, is 17.4 orders of magnitude down from "milli", so
noise_RMS = 0.001 * 10^-17.4;
Calculate a random signal of "x" elements:
random = randn(x,1);
Scale it to the right "rms"
noise_RMS*power
