1.1.2.4.48 MAC_RT_MOD_SCHEME Enum

typedef enum {
    MAC_RT_MOD_SCHEME_DIFFERENTIAL = 0x00,
    MAC_RT_MOD_SCHEME_COHERENT = 0x01
} MAC_RT_MOD_SCHEME;

G3-PLC Modulation Schemes.

The list of all Modulation Schemes supported by G3-PLC spec.

Coherent Scheme supports worst SNR (about 3 dB) than Differential Scheme.

Differential Scheme provides a bit higher data rate because Coherent Scheme uses some carriers for pilots.

Coherent Scheme requires an accurate crystal oscillator. G3-PLC specifies that the frequency error must be less than 25 PPM.
