2.4.20b) only foresees gmsk modulation for deep space missions when symbol rates are greater than 20 msps because gmsk needs less bandwidth allocation compared to other modulation schemes like oqpsk.
Very High Rate Tm Downlink Using Gmsk With Simultaneous Pseudo Noise Ranging
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.
