So, it's generally right that a receiver adds noise due to physics (Johnson-Nyquist noise). So, yes, in any system, at least part of the noise in the received signal is caused by the receiver. There's also noise that is background noise from e.g. cosmic sources that happen neither in the receiver nor the transmitter (and also aren't other transmitters ...

Okay, I am not quite understanding your question. Let's start with the definition of the Gaussian, aka the Bell Curve, in its general form. $$ f(t) = \frac{1}{ \sigma \sqrt{2\pi}} e^{ -\frac{(t-\mu)^2}{2\sigma^2} } $$ $\mu$ is the mean, and represents where the peak occurs. $\sigma$ is the standard deviation, and identifies where the inflection points ...
