As far as the PHY layer is concerned, CR can communicate with various radio-access technologies in the environment, or it can improve the quality of communication depending on the environmental characteristics, by simply changing the configuration parameters of the GMSK system and the SDR interface.

SDR Based Energy Detection Spectrum Sensing in Cognitive Radio for Real Time Video Transmission

EDGE improved GPRS rates by using a modulation scheme of higher spectral efficiency, 8-PSK (phase-shift keying), which transmits three bits per symbol, while GMSK transmits only one bit per symbol.
