Remove CW matched filter block
...
CW decoding using match filtering is pretty much useless in LEO.
The information about the tone frequency is very rare and carrier
oscillations during the satellite pass reduce significantly the
performance.
The new next CW decoder is based on the autocorrelation of the received
signal.

lookup tables for fast processing times. The implementation is quite
generic and modular supporting user defined polynomial masks and seeds.
The lookup table is created during the initialization without any
runtime overhead.
