* PLL: Able to *correct* small frequency errors: yes, but a frequency

Hi Marc, Jeff, all
Thanks for your reply.
(Also thanks to everybody who replied off-list.)
Hum.. looks like a good mental overview of all the blocks useful for PSK
would be good start for myself.
I did know about the "PLL Carrier-tracking block", but I had not yet
heard of this "FLL band-
Pretty much.
The FLL band edge system in GNU Radio does the following:
1. have a filter that extracts the energy "around the place where the
upper edge of where the signal is supposed to be", and around the lower edge
2. compares energies in both
3. multiplies the signal with e^jft, while adjusti
I think the general idea is that some signals have no carrier that a PLL
could lock onto. The FLL Band-Edge centers a signal using the shape of a
specific signal (the matched filter being used).
