| Dec 18, 2019 at 23:25 | comment | added | Dan Boschen | Do course acquisition if your carrier is more than 1/4 of the symbol rate off if you are using the Gardner TED (as a rough guide- please evaluate your carrier estimation SNR and overall performance as you vary the carrier offset to test) | |
| Dec 18, 2019 at 23:21 | comment | added | nancy | Can i always do carrier recovery after timing with 1 sample/ symbol. If my carrier offset is high i may do coarse offset aquisition followed by timing and then carrier recovery. When should i do carrier recovery first with say 4 samples/symbol. Does the Nco inside carrier recovery works at still higher rate? Thanks | |
