Currently the digital modulation used in telecom is GSMK
GMSK is a form of modulation used in variety of digital
radio communication systems.It has an advantage4s of being
able to carry digital modulation while still using the
spectrum efficiently.
One of the problems with other forms of phase shift keying
is that the sidebands extend outwards from the main
carrierand this can cause interference to the other radio
communication systems using nearby channels.
