Hi,
I'm trying to put the Barker correlator in the FPGA. This should greatly
improve the SNR of the BBN 802.11 code.
The plan is:
64Msps complex w/11MHz info -> Barker Correlator -> Decim by 16 -> 4Msps
complex with 1MHz info
instead of
64Ms complex w/11MHz info -> Decim by 8 -> 8Msps com

George, thanks for the information!
I would be very surprised if the USRP design did not intend to allow for
RF grounding to a case, but I supposed it's possible. Good grounding is
essential to good RF performance, especially with the proximity of the
analog and digital circuits.

In the existing code, methods on these objects are only called by the

thread safety.

The error message shows a different file name--is this something new
that you wrote? Also, the line numbers don't match the usrp_rx_cfile.
