Hi, These are programming questions for your application, unrelated to uhd. Your language is also a bit strange. Let me explain:
1) You take the output signal from your usrp and if it is larger than a threshold value you store their index to a vector. I imagine that the threshold is some kind of amplitute. To compare it to your samples, you need to find the corresponding amplitude: log10(hypot(Q, I)) Where Q is the real component of your sample, and I the imaginary. You can store that value to a new vector. Or simpler you can compare Q^2 + I^2,since log10 and sqrt do not add anything useful.To read from usrp use: uhd_rx_streamer_recv On Wed, Jan 25, 2023 at 9:49 AM <seckinonc...@gmail.com> wrote: > Hello USRP Users, > > I am new to UHD C++ API.
