Minimum-Shift Keying

    Last Modified: February 6, 2018

    Minimum-shift keying (MSK) is a special case of 2-FSK with a frequency deviation of 1/4 times the symbol rate. MSK uses a half-cycle sinusoidal pulse, thus making the phase change linear and keeping the side lobes low to control adjacent-channel interference.

    When differential encoding is enabled, the bits are encoded as yn = bn XOR bn-1, and then mapped according to the symbol map.
