I need to use the awgn() function in some of the work I am doing. Since the outcome critically depends upon how the noise is added, I wanted to know about the inner workings of awgn(): how is the power defined/measured, how is the noise added etc. I looked at the MATLAB help but it neither gives these details nor it points to the reference it implements. I would be grateful for any help on this regard.

If it's not a built-in fcn you can type:
edit awgn.m
and see what's inside.
