I mean S-parameters in wireless network. How can I  use  directional couplers in wireless network to do this?


Thanks a lot,

Hi all,


I have tried to use USRP B210 and GNUradio to send and receive signal, and now I want to get the network’s scattering parameters. But I don’t know how to get them using the software.


Is there anybody can give me some advice?


Thanks in advance.





You mean S-parameters, such as you'd get from an RF network analyser?

You need extra hardware to do that--directional couplers for measuring forward and reflected power, etc.
