[Discuss-gnuradio] Looking for VERY simple example

[James Aldous]

Hi discuss-gnuradio,

 

I have what is likely a very simple question that I am hoping someone could answer without too much trouble. Perhaps I just overwhelmed at the flexibility of GNURadio or have forgotten all my signal processing class topics, but I haven't been able to find an example of how to make GNURadio perform what I assume is a very simple task.

 

I want to be able to monitor an unmodulated 1 Mbps data stream at a single frequency, basically just turning the waveform into binary digits, and then analyze the stream to look for a certain pattern that identifies the beginning of a data packet which I can then capture and unpack into a data structure for further processing.

 

Is this something that can be done with existing GNURadio blocks and some Python code or will I need to write my own custom block?

 

Any pointers to examples would be greatly appreciated.

 

Thanks,

 

Jim
