If someone has ever measured Quality of service of received data (using any

loss rate/Bit Error Rate (or any other metric) with USRP & GNU Radio without
any error correction (ARQ,FEC) mechanism (but no problem if you have with
error correction mechnism) then please share your results here.
Actually without and error correction mechanism, with FSK, I am getting
almost half of my data lost. I was thinking that it may be improved by
adding some error correction mechanism. Or this high data loss is because of
some implementation errors...What do you say ??????????
We have no idea what your actual setup is, so we have no clue whether or
not error correction will truly help you.
It's like saying my computer crashed, and asking if a new hard drive
will help. Who knows, it all depends :)
Some questions that might help:
- are you using coax?
- are you using antennas?
- what kind of gain are you using?
- what kind of physical conditions?
- what bitrate are you using?
- are you seeing underruns at your receiver?
