Description: Minimum Shift Keying (MSK), uses two frequencies which are separated by 1/2T and phase discontinuity is avoided in symbol boundaries. Further, MSK transmission can also be visualized as a variant of offset-QPSK technique, where sinusoidals are used for pulse shaping instead of rectangular.
