55. Write the advantages of MSK over QPSK.

Advantages of MSK over QPSK:

i. In QPSK the phase changes by 90degree or 180 degree .This creates abrupt amplitude variations in the waveform, Therefore bandwidth requirement of QPSK is more filters of other methods overcome these problems , but they have other side effects.
ii. MSK overcomes those problems. In MSK the output waveform is continuous
in phase hence there are no abrupt changes in amplitude.
