What is GMSK used for?

GMSK is most notably used in the Global System for Mobile Communications (GSM), in Bluetooth, in satellite communications, and Automatic Identification System (AIS) for maritime navigation.

What does GMSK mean?

Gaussian minimum shift keying (GMSK) is a form of frequency shift keying (FSK) used in GSM systems. The tone frequencies are separated by exactly half the bit rate. It has high spectral efficiency.

What is GMSK in digital communication?

The Gaussian Minimum Shift Keying (GMSK) modulation is a modified version of the Minimum Shift Keying (MSK) modulation where the phase is further filtered through a Gaussian filter to smooth the transitions from one point to the next in the constellation.

What is the main advantage of GMSK?

The biggest advantage of using GMSK is that it reduces the sideband power, reducing out-of-band interference between signal carriers in adjacent frequency channels. GMSK provides high spectral efficiency.
