Nice work Charles.It is interesting to see that S2 has some amplitude modulation. It may face similar issues to DVB-T for power amplifiers and distortion. Is pre-distortion possible?
Hi, in truth all coherent phase modulations have instantaneous zero power crossings, making them AM in all but name. Now CPM (Continuous Phase Mod) in all varieties does not suffer this. Hence GMSK. See Dr Kamilo Feher.ISBN 0-13-098617-8 - cheers, IanW.
