Thanks!  Worked great.  At least this got me reading up on how cmake goes through the sub-directories.  Starting to make some sense. Thanks, Lou On May 28, 2016, at 06:55 PM, Johnathan Corgan wrote: On Sat, May 28, 2016 at 3:35 PM, Louis Brown wrote:   Does anyone have an example CMakeLis

Hi, Have GNURadio 3.7.9.2 installed on Ubuntu 15.10. I have been running simple_ra but don't believe that is germane to the problem at hand. I am running simple_ra_receiver under debug (have seen segmentation errors in libc in the past and trying to narrow down) but, again, don't thin

Does anyone have an example CMakeLists.txt to build something very simple like dial_tone.cc?  I DON'T want to do this in the GR source tree, rather just have simple ~/dial_tone containing the single *.cc and CmakeLists.txt.  I have learned enough c++ now to work through the guided tutorials, bu

2016-05-28 Thread Marcus Müller
Hi Gerhard, if I interpret your interpretation correctly, you assign a 1 to "long period", and a 0 to a "short period"? That would be an FSK inside an FSK; such systems exist (often for things like put data on a readily available FM modulator), but from the picture of your signal it's hard to tell

Hi Jose, so, the flow graphs in the tutorial do timing and frequency synchronization, but what they don't do is any kind of framing: you just won't know if the first bit you decoded is a the first bit of a byte, or from somewhere in the middle; that's what you're seeing here, probably! Best regar

Hi all, I am studying the tutorial 7: PSK Symbol Recovery. For it, I am using the mpsk_stage6.grc example flowgraph. But I am trying to simulate a transmition of a txt file. I can see the decoded signal on the scope perfectly but I would like to save this received file. According the tutorial, aft

Hi Jan, thanks for the feedback! PFBs are a topic I discussed with my mentors and we decided to not use them because of the following reasons. When using PFBs, there is a trade-off between band resolution and calculation effort (few filters lead to low number of possible frequency bands, many filt

Hey Sebastian, great work in your first week. Looking pretty good. One question though. At the end you propose to seperate the signals with a filterbank of xlating FIRs. Is there a use case or a way to do that with a polyphase filterbank? Cause multiple FIRs are going to become a major burden for
