WebMSK can be viewed as either a special case of binary continuous-phase frequency-shift keying (CPFSK) or a special case of OQPSK. When MSK is viewed as a continuous phase modulation (CPM) scheme, MSK is a binary modulation with interval Tb, but as a quadrature scheme, it is a quaternary modulation over a double interval 2 Tb.
