[Discuss-gnuradio] GNU Radio Project Call Today!

Hi all, we'll have our first 2018 project call today. Join us on IRC or Slack, and we'll be posting the links to watch on YouTube or to join on Hangouts there. Cheers, Martin ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org

Re: [Discuss-gnuradio] Is it safe to use get_tags_in_range within forecast?

Hi Markus - I think you'd be safe using a 1:1 sync block; ignore forecast since it's just an estimate & at least some of the time your block is copying 1:1 so it's kinda in the right ballpark; then in ::work() retrieve all of the rags in input range & if your special one is found then copy the

Re: [Discuss-gnuradio] How to count number of samples in a packet?

Hi Dara - Welcome to GNU Radio! Sounds like you have a fun project to get yourself motivated. It sounds like what you're looking for is, when using the provided tx_ofdm.grc flowgraph, how to convert from an input packet of data of some arbitrary length into the OFDM frames so-as to add on the USRP

Re: [Discuss-gnuradio] Softbits in gr-ieee 802.11 ?

I'm not sure if I understand you correctly, but you have to differentiate what performance you mean. IT++ might have better decoding performance (since it's using soft-bits), but the SIMD implementation has better computational performance (i.e., needs less CPU). To be honest, I didn't do a

Re: [Discuss-gnuradio] Softbits in gr-ieee 802.11 ?

Thanks for confirming. I believe that IT++ version will work with corresponding GNU Radio version. Also what do you think (since you have developed the code for long time :) ) : IT++ version will be as efficient as the current one? I mean the current version uses SIMD for Viterbi. I have tested

Re: [Discuss-gnuradio] GNU Radio v3.7.11.6 no attribute to byte array error

Marcus, I have now checked the patch, and I believe that it was an attempt by a user to resolve the issue. The Debi and bug as far as I can tell is unresolved. As a workaround it only affects QT GUI so I'm now using WX. On 17 January 2018 at 19:11, Müller, Marcus (CEL) wrote:

Re: [Discuss-gnuradio] Softbits in gr-ieee 802.11 ?

Hi, you are right. The current implementation does not use soft-bits but feeds hard bits into the decoder. In 2013, I used the soft-input Viterbi decoder from the IT++ library. http://itpp.sourceforge.net/4.3.1/convcode.html Best, Bastian On 01/17/2018 11:36 AM, sumit kumar wrote: Hi, I

[Discuss-gnuradio] How to count number of samples in a packet?

Hello gnuradio users, I am new to gnuradio and don't know much about it. I would like to make a burst transmission system based on OFDM. Regarding the previously discussed emails, I learned that the first and the last samples in a burst should be tagged with "tx_sob" and "tx_eob" , but I
