Hello USRP Users,

I am new to UHD C++ API. I have some questions about the application that I 
planned to develop. I have N320 and I got the signal from one channel and keep 
it in a vector as “buff”.  As you may know form examples.

1) How to take the envelope of the signal, then assign a threshold value and 
keep the index of the sample which is greater than threshold value in a vector?

2) After getting pulse’s TOA(time of arrival) and TOD(Time of Departure), how 
to take the fft and keep the frequency shift in a vector?

3) Buff get 2000 samples in one cycle in my configuration. How to arrange the 
fft size and buff size to have a real time operations? Can processing delay be 
fixed for each cycle?
