We're attempting to use the 802.15.4 (OQPSK) blocks that a UCLA
wireless group wrote, available here:
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
We are generating absolutely no overrun/underrun between the
transmitter and receiver, so I'm not exactly sure what could be the
Any other ideas?
Does the code do frequency offset correction? What about timing?
