[Discuss-gnuradio] feedback loop in gnu radio
I am using a GRC flowgraph for testing the energy detection algorithm for cognitive radio.I want to update my threshold for probability detection by estimating the SNR of the channel. However, for this, I need a feedback loop, which I want to know how to implement. Regards, Sagnik Basu B.

Re: [Discuss-gnuradio] feedback loop in gnu radio
Hi Sagnik, right now, you can't build loops out of stream connections. That has causality reasons – if you had such a loop, and the "merging" block at the start of the loop would need input on both channels, GNU Radio couldn't guarantee your flow graph could ever start¹. If you can live with a loosely–coupled feedback loop, message passing would be an appropriate method: You can pass messages from any block to any block without any restrictions - but also, without backpressure. See chapter four or five of http://tutorials.gnuradio.org . (If you haven't already, read the tutorial from the start – I think it's rather nice!) Best regards, Marcus ¹ In fact, that restriction has historical reasons, and we know we could remove it in some cases, but we didn't, so far. I used to have an experimental branch where we didn't have that restriction, but then a lot of our not-directly-stream-connection-related stuff breaks; basically, a lot of algorithm in GNU Radio's internal data handling depend on the Flow Graph being cycle-free.

Re: [Discuss-gnuradio] GSL_FOUND both TRUE and FALSE
A patch was applied a couple weeks ago because gr-dtv wasn't running the same check for GSL that the previous libraries were (in CMAKE), which caused the same problem. Perhaps this is the same issue? Really depends exactly which version you were running. If you are running from git between I think October and recently that could be it. If so, then just update your repo and you should pick it up.

Re: [Discuss-gnuradio] GSL_FOUND both TRUE and FALSE
I would take a look at the FindGSL.cmake script. I suspect the issue is related to the change to run FindPackage twice. Perhaps the pkgconfig detection isn't pulling in the variables the second time so they are being set to nulls? For a quick test, I would try commenting out the "find_package(GSL)" in the gr-dtv CMakeLists.txt and see what happens.
