Greetings,
I am new to GNURadio(and Linux, and Python, etc, etc). I am a comms/RF engineer trying to take advantage of this great development environment and the USRP. In the past few days I've developed an FSK receiver for use in a particular application. I now have recovered data that I can output to a file, scope, etc.
I have arrived at my next challenge.. I need to do something useful with the data, which means achieving byte alignment. The frames are 51 bytes long, and begin with a two byte sync word. Well, actually the frame begins with an 11 bit barker code, but in most cases, the remaining bits of the second byte aren't used. I would like to parse the incoming data, identify the barker code, align the data accordingly, and output a 51 byte chunk from a block. In short, I need frame aligned data.
Before I begin coding, I wanted to see if anyone has something written that could be modified to handle this. If not, I would certainly welcome any suggestions for implementation.
Happy Halloween!
-John
