Re: [Discuss-gnuradio] [GSoC 17] DAB: Updates

Hi All, Nice to see some discussion on DRM. Well, I also used gr-drm and is not fully supported like multiple audio and data services. DRm also uses tow audio codecs namely AAC and xHE-AAC. gr-drm supports only AAC. I don't know about any xHE-AAC encoder/decoder open source available. If anybo

Hello Martin, As of now I am thinking this as an OOT module. Features upto widgets are added on master. I will merge remaining sinks to the master from develop branch. I will try to add some screenshots in upcoming blog post and a screencast by next Monday. On 9:24am, Fri 18-Aug-2017 Martin Brau

Yes. There's a whole category "impairment models" in GRC. Best regards, Marcus On 08/18/2017 07:11 PM, mohammad nejati wrote: > > Hi , > is there any block ( or OOT module) for simulating power amplifier non > linearity ? > > > > ___ > Discuss-gnuradio

Re: [Discuss-gnuradio] [GSoC 17] DAB: Updates

Hi Rafael, I don't really see how these are a real problem – if you'd need another encoder, just drop one in – shouldn't be that hard to code if you know which encoder you'll want to use. Of course, you'd need to adjust some bit flags in the flow – but that shouldn't be that hard. So, it's kin

[Discuss-gnuradio] PC for gnuradio

Does gnuradio work on a raspberry Pi or beagle bone ? Once you develop a gnuradio flow graph is it possible to say turn that into a software program that runs ? For example you develop a satellite ground station for gnuradio can u then compile the application ? Are there any sdr that are act

Re: [Discuss-gnuradio] [GSoC 17] DAB: Updates

gr-drm is working fine, but there are some limitations (one audio service only - MDI input support would fix this, only faac AAC LC encoder, ...), and as far as I know, there are no open source ISDB-T transmitter implementation. GSoC always help. Rafael Diniz On 08/18/2017 11:03 AM, Martin Braun

Kartik, I'd love to see more screenshots and screencasts in your blog posts. Also, what are your plans for merging or upstreaming this, if you have any? Cheers, Martin On 08/11/2017 11:34 PM, Kartik Patel wrote: > Hello all, > > This week I almost completed waterfall sink for float values. For

The burst shaper actually has a manual page: https://gnuradio.org/doc/doxygen/classgr_1_1digital_1_1burst__shaper__cc.html The resampler will give you some rolloff, so you have a more usable digital signal going to the USRP. Check out uhd_packet_?x for details on how the USRP is configured. Its s

I wonder when we'll have a DRM app like this one. At least the mux and codec part are very similar could be shared with DAB. May be next GSoC? DRM and ISDB-T are the major wishes here from Brazil. ; ) Regards, Rafael Diniz On 08/18/2017 10:01 AM, Moritz Luca Schmid wrote: > Hi, > > "A DAB/DAB+ t

Hi, "A DAB/DAB+ transceiver app" is now called "DABstep"! I added a developer mode to the app, for all users who want to watch the spectrum, a constellation plot, ... while listening to noise-free DAB+ audio ;) Here
