I am unable to differentiate GMSK and GFSK. How do the modulation techniques differ in Tx?

How do their receiving techniques differ..?

    $\begingroup$ With GMSK the frequency modulation index is 0.5. With GFSK, the frequency modulation index is larger than 0.5 (the signaling tones are farther apart). $\endgroup$ – Andy Walls May 14 '17 at 10:19

The receiving techniques used for GMSK as an FSK work for GFSK.
