[Discuss-gnuradio] add the outcome of bit rate in ofdm benchmark_tx.py

Hi everyone, I am new comer to gnuradio, right now I want to use USRP N210 to send and receive package. I want to get the average data rate when I transmit. Does anyone know how to get how many bits I transmit in payload? Thanks. BTW, I use benchmark_tx and benchmark_rx to transmit.

Re: [Discuss-gnuradio] UDP streaming and queue-ing incoming ts stream to be tx'ed by dvb-s2

ok, I got it did some reading in the mean time. Who (in my setup) is the 'client' and who is the 'source'? I guess: the program who makes the ts stream is the 'source'/server and the gnuradio is the 'client' who requests data from the server? correct? Van: "Marcus Müller"

Re: [Discuss-gnuradio] UDP streaming and queue-ing incoming ts stream to be tx'ed by dvb-s2

ZMQ is a kind of a socket framework; In GRC, you'll find the category "ZMQ Blocks", and you'll find infos on how to use it from .Net on http://zguide.zeromq.org/page:all (e.g. many of the examples in the beginner's guide are also available in C#) Cheers, Marcus On 04/19/2017 10:23 PM,

Re: [Discuss-gnuradio] ATSC Decode Issues

Unless you have a many core CPU (greater than four), the ATSC decoder usually doesn't run in real time. You have to capture an IQ stream to disk first and then demodulate it in non real-time. Ron On 04/19/2017 09:14 AM, Ghost Op wrote: Hi all, I'm having an issue getting ATSC to decode and

Re: [Discuss-gnuradio] UDP streaming and queue-ing incoming ts stream to be tx'ed by dvb-s2

Hi, To be clear, the UDP or TCP sender is a .net program on windows... the receiver is of course gnuradio on Linux with limesdr or hacksdr. Can you clearify what this ZMQ is? where can I find info? Will it be usable in my given context? kind regards Van: "Marcus Müller"

Re: [Discuss-gnuradio] UDP streaming and queue-ing incoming ts stream to be tx'ed by dvb-s2

Hi Guy, you're right, UDP alone doesn't work here. However, the ZMQ PULL source would work :) ZMQ is available for practically every major programming language, so that might be an easy to use choice (or you use the matching ZMQ PUSH source in GNU Radio on the computer that sends the TS file via

Hi Dane, good work! Especially the custom blocks. Regarding 1.: I'm not 100% sure I understand what you mean. Could you maybe elaborate on what you want to be able to do? Regarding 2.: Since this really seems to be an FSK system, try using the "Frequency Mod" block, fed (for now) from a vector

Hi Group, I want to send a ts stream with gnuradio and dvb-s2. I can already record (make) a ts file and copy it to Linux to be send by gnuradio running dvb-s2. This works ok. But now I want to send the ts file live to the Linux gnuradio pc via network. But I think I need some queueing or

Dear Marcus, Thanks for the explanation. I was making .dat file correctly from file sink but was reading it incorrectly in Matlab. I was using fread command to read the file but it turned out specific matlab scripts (read_complex_binary.m to be exact) are to be used when parsing grc saved complex

Hi all, I'm having an issue getting ATSC to decode and I was hoping someone who has done it successfully may have some pointers. Here's the scenario Basic SDR antenna connected to an LNA4ALL feeding into an Airspy sampling at 10 MSPS using the attached flowgraph. I get a TS file and don't

Re: [Discuss-gnuradio] why the prototype of pmt_t is intrusive_ptr

That was done for performance reasons, so that the refcount and the object are close together, if I remember correctly. You can of course write your own pmt_t alternative, or change GNU Radio's source code, but I'd argue that would probably be quite some work. Why do you ask? Best regards,

Hey Ammar, do you store real and imaginary parts of the complex output of the USRP separately? How do you read the file in Matlab? It would probably help if you could elaborate on your problem a little more. Cheers, On 04/19/2017 08:46 AM, Ammar Mahmood wrote: > Dear all, > > I am trying to

Dear all, I am trying to save noise samples using file sink to verify that noise follows Gaussian distribution. I mat file is made by the file sink block. When I read this mat file in mat lab, it only shows the positive samples and does not have negative samples whereas it should have negative
