This block makes hard decisions about the received symbols (using a constellation object) and also fine tunes phase synchronization.
The phase and frequency synchronization are based on a Costas loop that finds the error of the incoming signal point compared to its nearest constellation point. The frequency and phase of the NCO are updated according to this error.
- constellation of points for generic modulation, see Constellation Object
- Loop BW
- Loop bandwidth of the Costas Loop. A good starting point is 2pi/100, or about 0.06.
- Min Freq Deviation
- minimum normalized frequency value the loop can achieve
- Max Freq Deviation
- maximum normalized frequency value the loop can achieve
