I'm looking for some tips on how to improve file transfer using two USRP's. I understand the method I'm using might be fairly crude, but I'm just starting out.
Problem is I'm dropping a lot of data out of the file (receiving missing parts of a string and such). This gets really bad when one of the USRP's is moving.
File Source > Packet Encoder > GMSK Mod > USRPB100 Sink
USRP B100 Source > Xlating FIR Filter (LP 100khz) > GMSK Demod > Packet Decoder > File Sink.
I want to try and add some FEC, however, the only FEC blocks that ship with GNURadio say "This package is for continuous data, not packetized". Any FEC tips would be nice.
Is there anything wrong/bad with this flow graph for sending files? Or perhaps a better solution? I understand there could be a heap of problems not relating to GNURadio, but I'm sending the files in the middle of a very large (>1mile square) open field , with good line of sight.
Cheers,
Ken
