Hi Tellrell,
I know you can find the PSDAh, 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 confused; sorry!
So, ultimately, if the way that I'm implementing the algorithm is correct thus far, I'm looking for a way to display(graphically or otherwise) my result or the avg power.It's impossible to say whether an algorithm is correct without specifying what it should be doing - so maybe we need to take a step back: 1. you want to do detection of IEEE 802.15.4 signals. Which PHY
are we talking about? There's multiple physical layers for that
standard. The DSSS types aren't really … friendly towards energy
detection at all. Best regards, Marcus On 09/21/2017 11:32 AM, Tellrell White
