GAUSSIAN MINIMUM SHIFT KEYING (GMSK) - Rutvij C
www.rutvijjoshi.co.inINTRODUCTION TO GMSK |Gaussian Minimum Shift Keying (GMSK) is a form of continuous-phase FSK in which the phase change is changed between symbols to provide a constant envelope. Consequently it is a popular alternative to
A Simple Signal Shaper for GMSK/GFSK and MSK Modulator ...
www.oscium.commethod of realization, MSK is derived as ordinary FSK with the modulation index set to 0.5. The modulation index of 0.5 corresponds to minimum frequency spacing that allows two FSK signals to be coherently orthogonal, and the name minimum shift keying implies the minimum fre-quency separation that allows orthogonal detection.
