Gaussian Minimum Shift Keying

Smooth MSK with Gaussian filter, GSM standard

Real-World Applications

The core technology of 2G GSM mobile networks! Billions of GSM phones worldwide use GMSK. Also used in AIS ship automatic identification systems. Gaussian filtering makes the spectrum more compact, reducing interference to adjacent channels.

Experiment Steps

1. BT Product: GSM uses BT=0.3
2. Compact Spectrum: Faster sideband decay
