[amsat-bb] Good results with polyphase filterbank from Theseus Cores

[Michelle Thompson]

Phase 4 Ground has had some good results with the RFNoC polyphase
filterbank from Theseus Cores.

Having a fast efficient polyphase filterbank for our payload is just as
important as getting an LDPC decoder for the ground!

Here's a video update on this week's work in the lab:

The hardest parts are coming together! Still plenty to do, but these blocks
have been two years in progress. Seeing them start to work over the air is
a real thrill.
