Oh, and I might be the only one who calls this the “FLL band edge
filter” specifically to point out that this is only one possible
implementation of an FLL for coarse frequency tracking. Other
algorithms are welcome
Thanks for these pointers. For future reference (and the mailing list
- The paper “Let’s Assume the System is Synchronized” is a good
introduction and provides a great and simple explanation.
- Harris’ book “Multirate Signal Processing: for communication systems”
is the more complete version, down to polyphase implementation
- I should have realized this is a way to implement an ML Frequency
correction for RRC spectra without a-priori knowledge. This is more
generally derived in “Synchronization techniques for digital
receivers” by Mengali/D’Andrea, and probably many other places.
 In general, Fred Harris books and papers are more fun to read,
