pler tracking time between slow and fast.

The HF modem implementation is able to track
the Doppler offset present in the signal at the
receiver.
Therefore the modem can handle such fre-
quency offsets automatically and ensure su-
perior performance over a wide range of
Doppler offsets.
Slow tracking can handle higher offsets, but
the signal acquisition takes longer.
Fast tracking limits the range of frequency off-
set which can be detected.
