Detection of Burst Signals in LabVIEW

I want to develop a project that processes incoming signals and can detect burst signals. Could anyone please provide guidance on how to approach this?

Suppose I say to you "I have a signal.  Does it have a burst, and if so, where is it?"

 

Do you see the problem with this (i.e. "your") question?

  • What is a "signal"?
  • How is a "signal" represented?  More specifically, what data type is used to store it?  [Since this is a LabVIEW question, are you using a Waveform?]
  • What is a "burst"?  What criteria do you use to distingish "burst" from the rest of the "signal"?

When you provide an answer to these questions, you can begin to think how you would want to distinguish Burst from Signal.  Come up with a criterion, and then think how you would implement this idea in LabVIEW.  As a way of testing your prototype LabVIEW code, I recommend generating two Waveforms, one of a typical "Signal" and one with a "Signal" + a "Burst", which I imagine as a Waveform that is zero everywhere except for an interval where it takes on random values (over some range to "stand out" from the Signal).

I will take signal from either USRP or VSA. Datatype of signal will be Real Time IQ which will be saved in array of complex numbers or I and Q arrays. You asked me another question: What is a "burst"?  What criteria do you use to distinguish "burst" from the rest of the "signal"? I have the same question. I also want to know which criteria and technique should be applied to distinguish between burst and rest of signals.

Thanks.  I have no experience with Software Defined Radio, so can't really help you.  However, there is a Forum here on USRP Software Radio where you might find more help ...
