Introduction to Digital Modulation

Binary frequency shift keying (FSK): a(t)=1 ζ(t): ζ(t)=2 π(∆/2)t + φ1 for symbol “1” ζ(t)=-2π(∆/2)t + φ2 for symbol “0” where ∆is the frequency separation between the signals for symbols “1” and “0” respectively, φ1 and φ2 are any constants in [-π,+ π]. The modulated signal is

method 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.
