Hi, Martin, what exactly do you mean by:

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 > polyphase-stuff. > 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 -- Nemanja Savić
