Hi,
can you elaborate what you mean with "synchronized"? A CSI estimate can only happen when
the necessary pilots have been observed, and that will, due to finite speed of light,
necessarily happen at different times at different receivers.

defining the compiler and linker properties of your compilation units, with manual
"include_directories" things. Probably not a great idea! If you compare that with what
`gr_modtool` generates in its lib/CMakeLists.txt, you'll find how we'd, as a project,
would recommend
't part of your flowgraph :)
So, please do specify your question a bit more: What's your digitizing system, which rates
do you plan to work at, and show spectra (using the screenshot functionality of your OS)
of what you get, and if possible, a sketch of what you want.
Best regards,
Marcus
That'd be probably versions shortly before 3.4.2 or so

What daughtercard do you have in your N210? What have you set the gain
to on the radio block? What is the
output level of the signal generator?
Hi Muhammad,
you're connecting the wrong kinds of things there. The QT GUI Inspector sink takes output
of the Signal Detector block, from gr-inspector itself.
gr-inspector has an examples/ directory. Please refer to that.
