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.
