GMSK (Gaussian Minimum Shift Keying)

GMSK (Gaussian Minimum Shift Keying) is a digital modulation technique used in wireless communication. It encodes data by smoothly changing (or shifting) the phase of a signal in a way that minimizes abrupt transitions, which reduces interference and improves clarity. The "Gaussian" part refers to shaping the signal with a Gaussian filter before shifting, further reducing side effects like spectral spreading. Overall, GMSK allows reliable, efficient data transmission with less interference and better bandwidth utilization, making it ideal for mobile and radio systems such as GSM networks.
