-    """The goal of the automatic gain control is to set the 
-    RX gain to a value at which all received amplitudes can 
-    be detected. This means that the maximum possible amplitude 
-    should be quantized at the highest possible digital value.
-
-    A problem we have to face, is that the estimation of the 
-    maximum amplitude by applying the max() function is very 
-    unstable. This is due to the maximum’s rareness. Therefore 
-    we estimate a far more robust value, such as the median, 
-    and then approximate the maximum amplitude from it.
-
-    Given this, we tune the RX gain in such a way, that the 
-    received signal fulfills our desired property, of having 
-    all amplitudes properly quantized."""
