Hi,
I want to use GPS time data for synchronization of two USRP boards. I
already have the USRP daughterboard for GPS.
I came accross with gps-sdr but it seems does not work with the latest GNU

I do not know if it has already been done, or is there any project go
Great.
Sit in front of your keyboard and during the time you wrote this
complaint you could have made a start on the code. If you need to build
flavors of MIMO and you cannot even make this beginning yourself, you
are in the wrong end of this business.
This is a user contributed project.

and, more specifically, less than a couple of hours experience with

If you execute the benchmark_rx.py file with the following command:

I think not. The Peakdetector(with TH factor Rise and Fall) works and the

DBPSK is differential BPSK. However our transmitter sends 'ordinary' BPSK not
the differential version, so I cannot use the DBPSK version.

I looked and found the benchmark_rx. The version in the 'digital' folder does

However the benchmark_rx in the 'digital-bert' folder does have BPSK in it.
