[Discuss-gnuradio] MSK de-/modulation

2006-05-08 Thread Thomas Schmid
Hi, I figured out by now that the problem is not on how I decode MSK within GNURadio, but that the signal I receive from the USRP is very strange. To verify what my test code does, I loaded the received message in octave and plotted the I and Q phases. A sample plot is added to this email. I samp

Hi Matt, Can you give me some pointers on what I would have to tweak in the GMSK code? I read up on MSK but most demodulators I found use integration of the I and Q phases and then proper slicing. I can see how that works if I have synchronization, but I don't know how to achieve that. Here some
