Re: [Discuss-gnuradio] Continous PSK/ FSK transmitter with discrete data

I've got a pretty complicated example at https://github.com/dcajacob/gr-ccsds However, it could be simplified by removing the convolutional encoding. On Mon, Mar 12, 2018 at 10:15 AM Mehmet Ozcelebi wrote: > Dear All, > I have been playing with the blocks shown in " Guided Tutorial PSK > Demodu

[Discuss-gnuradio] [GSoC18] Application period started!

Hi all, the application period has started today and we are eagerly awaiting your draft proposals! Please make sure to submit as early as possible and (optimally) also well before the deadline (March 27) - we really want to help you to craft a good proposal and to set you up for success righ

Re: [Discuss-gnuradio] FFT bin ordering

Hi Marcus, Sorry for the delay, thanks for the elaborate reply. My use case is quite specific actually, in that Im looking for a peak in a specific part of the spectrum. I had another look and failed to reproduce the problem I was having so maybe it is a problem between keyboard and chair issue bu

Re: [Discuss-gnuradio] Wideband OFDM Reference Implementation

Hi Sinan, GNU Radio itself comes with an OFDM implementation. Since it's all software defined Radio, it's totally agnostic of the bandwidth you use it with, assuming sufficient compute power. Also, there's gr-ieee802-11 as you might have noticed, which implements the WiFi PHY. Best regards, Mar

[Discuss-gnuradio] Wideband OFDM Reference Implementation

Hello, I am wondering, is there any good reference implementation of wideband OFDM (up to 20 MHz) available that you would recommend? Best, Sinan ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-g

[Discuss-gnuradio] Continous PSK/ FSK transmitter with discrete data

Dear All, I have been playing with the blocks shown in " Guided Tutorial PSK Demodulation" and want to implement my own Transmitter/ Receiver pair. First I tried to replace the "Random Source" or "File Source" blocks with a "Socket PDU-TCP Server". I observed that modulation happens only when I

Re: [Discuss-gnuradio] Convolutional decoder

Use the FEC Extended Encoder/Decoder with the CC Encoder/Decoder definition blocks. This assumes you are implementing a continuous modulation, like the CCSDS standard and not a bursty system. On Mon, Mar 12, 2018 at 9:03 AM samuel verdon wrote: > Hello everybody, > > > > I am looking for a convo

[Discuss-gnuradio] Convolutional decoder

Hello everybody, I am looking for a convolutional decoder for my ground station. I have found the ccsds 27 which does the 1/2 code rate. Unfortunately I would like to have ¾ code rate. I found the cc decoder definition with the FEC extended decoder. In documentation, it is written that it canno
