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

Hi Ivan, The TX/RX and RX2 are ports on the same receiver channel. As Julian says there are two receivers, A and B. For a receive only application the RX2 ports are slightly better performing as they have one less switch that the signal passes through. Regards, Derek On 18/11/2020 14:01, Ju

Ivan, to the best of my knowledge, there should not be any RX1 port. Instead, you should have two (coherent) channels "A" and "B" both allowing you to select one out of two available antenna ports when receiving ("TX/RX" or "RX2"). Cheers, Julian On 11/18/20 10:31 AM, Ivan Zahartchuk via USR

Another question of interest is which channels are coherent? Rx1 and RX2 or RX1 and RX / TX? вт, 17 нояб. 2020 г. в 01:56, Ivan Iudice : > Right! > Be careful, DOA estimation using only 2 antennas works but it’s not so > accurate. > Enjoy! > > Ivan > > > Il giorno 17 nov 2020, alle ore 00:35, Iva

Right! Be careful, DOA estimation using only 2 antennas works but it’s not so accurate. Enjoy! Ivan > Il giorno 17 nov 2020, alle ore 00:35, Ivan Zahartchuk > ha scritto: > >  > > > > That is, in theory, I can simply start two streams from two channels and > further process them using cer

That is, in theory, I can simply start two streams from two channels and further process them using certain direction finding algorithms?

The two channels on an E310 are already time synchronized and phase coherent. You’d only have to callibrate and remove external phase effects. Sent from my iPhone > On Nov 16, 2020, at 6:15 PM, Ivan Zahartchuk via USRP-users > wrote: > >  > Hello. I am interested in the possibility of impl
