Right!
 Be careful, DOA estimation using only 2 antennas works but it’s not
 so accurate.

Hello I am trying to install RFNoC for uhd 3.15. As far as I understand, this version supports RFNoC. And in order for me to have blocks in gnuradio, as I understand it, I need to install gr-ettus. But when installing, I get this error The found UHD version (3.15.0.0-3build2) is not compatible with the version required (4.0). how can I be in such a situation? ср, 18 нояб. 2020 г. в 16:24, Derek Kozel <derek@bitstovolts.com>: > Hi Ivan, > > The TX/RX and RX2 are ports on the same receiver channel.

Hi Ivan, Try building with the gr-ettus maint-3.7 branch.
