What is the advantage of MSK over FSK?

MSK is one type of FSK modulation with less occupied bandwidth. This leads to less interference to the spectrum. MSK uses half cycle of sine wave for each symbol. MSK with Gaussian filter gives GMSK signal.

What is MSK of FSK?

Minimum shift keying (MSK) is a special type of continuous phase-frequency shift keying. (CPFSK) with h=0.5. A modulation index of 0.5 corresponds to the minimum frequency spacing. that allows two FSK signals to be coherently orthogonal, and the name minimum shift keying.

Why MSK is called Fast FSK?

Explanation: Minimum shift keying is sometimes also referred as fast FSK. It is so called because frequency spacing used is only half as much as that used in conventional noncoherent frequency shift keying.

What is the difference between FSK and Mfsk?

Multiple frequency-shift keying (MFSK) is a variation of frequency-shift keying (FSK) that uses more than two frequencies.
