Claims Versus Analysis
Walker claims that with VMSK, "Efficiencies up to 15 bits/sec/Hz are now being achieved in usable hardware with C/N ratios better than that obtainable using FM, BPSK or QPSK."
Analysis by third parties have concluded that "no ultra narrow band modulation (UNBM) method, which includes very minimum shift keying (VMSK) and VPSK, can have substantially greater efficiency than conventional methods."

Famous quotes containing the words claims and/or analysis:
“Who claims that the heathen’s view of the world is incorrect? Life gives you nothing! It is ruled by false gods! Nothing remains true to you but your own self; provided you remain true to it.”
—Franz Grillparzer (1791–1872)
“A commodity appears at first sight an extremely obvious, trivial thing. But its analysis brings out that it is a very strange thing, abounding in metaphysical subtleties and theological niceties.”
—Karl Marx (1818–1883)
