Hi,

Martin, what exactly do you mean by:

Preamble is indeed long. On the figure I attached in my first post it can
be seen the input and output od
synchronization M&M block. I am expecting this block to do synchronization
based on preamble.
In worst case I can meassure every pulse and make my own synchronizator,
which looks a bit ugly, but
works.

If you start with an oversampling rate of 4 you don't even need to do any

Not quite sure that I understand, but I am sampling signal with ca. 500k,
and symbol rate is 19.2k, so if you were thinking about oversampling after
bit slicer, yes i have oversampling of ca. 25.

In my receiver, after a bit filtered demodulated signal from quadrature FM
demodulator, I have a block, designed by myself, that does bit slicing. It
is basically simulation of a circuit that is used in
some receivers with min and max diode detector circuits. Since I am quite
sure this is not the usual way of doing this, how am I supposed to get
digital
pulses from demodulated signal.

Best
