Is this being deprecated because it doesn't work correctly? The reason should be mentioned. I have read it is buggy.
In my testing with 8PSK it does more harm than good, regardless the settings used.
Note: the modulus setting doesn't seem to mean the same thing as modulus in related components, and a modulus of 1 is used for QPSK in the tutorial.
Deprecating blocks seems like an annoying thing to do. Unfortunately, sometimes things that seemed like a good idea turn out to be a dead end. In this case, we now have better alternatives: Linear_Equalizer and Adaptive_Algorithm.
