Packet detector

Hi Marc!

Many thanks for the great work! PySDR was the ideal introduction to the world of sdr for me!

What I'm still missing is a routine that searches for possible packets in the iq data stream, since my modem only sends one packet every second.

Do you have any ideas? Regards, Manuel

Great idea! For a quick solution in the mean time, you could try taking the magnitude of the signal with np.abs() then thresholding it, should work for medium/high SNR signals if you manually tweak the threshold. You can also try np.diff(np.abs()) which will cause big spikes every time the signal goes from being off to on.
