GMSK Modulation constellations

1. EDGE coding schemes

MCS1-4 (this is not the

same as GPRS CS1-4)

2. Uses GMSK modulation

3. 1 bit per symbol

4. Constant power trace

3S/8 8PSK Modulation Constellations

1. EDGE coding schemes

MCS5-9

2. Uses 3S/8 8PSK

3. 3 bits per symbol

4. Utilises a 3S/8 rotation

every symbol to avoid

zero transitions

5. Power trace now varies

with symbol transitions
