Maybe we can bring this thread up one more time. Michael found me on
campus and I've been trying to help with this.
We're attempting to use the 802.15.4 (OQPSK) blocks that a UCLA
wireless group wrote, available here:
http://acert.ir.bbn.com/projects/gr-ucla/
Using file source/sinks, we can successfully encode/decode packets
with absolutely no packet loss. As soon as we connect the blocks with
the USRP, we experience relatively high packet loss (~2%) using coax
(very high SNR, low noise). I would expect 0% packet loss, as I see
using every single other modulation scheme in GNU Radio with
benchmark_tx/rx.
We are generating absolutely no overrun/underrun between the
transmitter and receiver, so I'm not exactly sure what could be the
problem here.
Any other ideas?
Does the code do frequency offset correction? What about timing?
