Matched Filter for Manchester Coding #1

Closed bemasher closed 1 month ago

bemasher commented 7 years ago

Have you looked at implementing a matched filter to handle the manchester coding in signal processing rather than after you've done bit-decision? You can avoid having to set any kind of signal strength thresholds if you design it a particular way.

I hadn't, so thanks for the tip. And thanks for documenting how you approached the signal processing.
