немного о том, что заявляют авторы. по сравнению с классическим КАМом

Up to 10dB system gain advantage
Up to 400% the distance
Up to 50% lower power
Up to 50% spectrum savings
Better noise tolerance
Major increase in speed
Lower cost and easier design
100% backward compatible

This is a really low grade form of marketing BS. The claims " up to 10 dB system gain advantage, up to 50% lower power, up to 400% greater distance, up to 50% spectrum savings, better noise tolerance, major increase in speed" violate Shannon's Limit. 400% greater distance means I could lower the power by 12 dB for the same distance. If I can also lower power by 50% then I have a 12+3 =15 dB improvement in energy per bit compared to the noise (Eb/No).
Not remotely possible. He also claims to get more bits (i.e higher speed) in half the spectrum while lowering the modulation order (alphabet). Nuts.
He is claiming all this is possible by "compressing the spectrum".
