What is GMSK demodulation?
The GMSK Demodulator Baseband block uses a Viterbi algorithm to demodulate a signal that was modulated using the Gaussian minimum shift keying method. The input to this block is a baseband representation of the modulated signal.
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.
How does GMSK modulation work?
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 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.
