Sorry for the confusing explanation, but yes, I'm trying to find the
average energy over frequencies.
1. What I'm doing, at least as a start, is signal detection of 802.15.4
waveform using energy detection focusing on the O-QPSK PHY operating at the
2.4 Ghz band. The O-QPSK PHY uses a 32 bit chip
Hi Tellrell,
> I know you can find the PSD
Ah, so you're actually after a PSD estimate – It wasn't clear to me what
you were looking for, because the FFT-> frequency sink flowgraph didn't
make sense. And you just said "average energy" (not "average energy over
frequencies"), so I was kind of confu
Thanks for the replies guys
Marcus I know you can find the PSD of a signal in both the time and
frequency domain. The only reason I'm choosing to use the frequency domain
is because it was one of the earlier methods that I learned about. That's
really all. From the archives I've read about people
You can use the qt gui vector plot to plot a vector. That means removing
the stream to vector block. You might have to add "vector" modes to some
blocks to do the other operations you want.

Hi Tellrell,
if you just need average power, why go to the frequency domain at all?
That doesn't make sense to me, but maybe I'm not getting the whole picture.

Hello MarcusYou are absolutely correct. Is there an existing sink that would
allow me to display avg power given some threshold ?

Hi Tellrell!
Why should both plots show the same? You send in completely different
signals!
