Jason,
I downloaded and compiled your program. Here are some remarks.
- I accidentally ran your program using UHD 3.9.LTS. It worked fine!
It even worked fine with Num Channels set to 2. I then realized my mistake
and switched to 3.10.
- I duplicated your results using UHD 3.10. Th

Correction: The thing I mentioned about all taps being phase shifted by the
same amount isn't always observed.
I tried it again with the same USRP, (and 2 USRPs with a MIMO) and I still get
different channels every time I start the flow graph.
Identifying multiple taps: the channel estimate I
Hello Users
I recently stumbled onto a problem. I need to implement a gain control
mechanism by left shifting bits of the received data, when the rx power is
considerably low. I need to define a settings register which controls the
shift amount, but I need to get access to this setting register us
Hi everyone,
Has anyone noticed unstable LOs or carrier frequency offsets when using
USRP B210s with board mounted GPSDOs?
We have recently been doing field tests using GPS-disciplined oscillators
for both USRP B210s and USRP N210 and occasionally both transmitter and
receiver flowgraphs lose GPS

Hello All,
Just want to note that NI 2921s use XCVR2450, which is half-duplex (cannot
rx and tx concurrently). B210s will work better, as they are full-duplex
2x2 MIMO.
