[Discuss-gnuradio] Mutex lock error

Hi, Today while donig some random testing, I had this error in complex_to_mag block. "boost unique_lock has no mutex: Operation not permitted." What could be the reason? Regards, Usman ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org

Re: [Discuss-gnuradio] DVB-S Receiver

There are some DVB-S receivers. See: https://github.com/EdmundTse/gr-dvb http://www.pabr.org/radio/leandvb/leandvb.en.html The leandvb project is current and based on gr-dvb. A good project might be to port leandvb back into GNU Radio. It should be noted that GNU Radio has a high

[Discuss-gnuradio] DVB-S Receiver

Hi all, I am doing my master degree in wireless communication and new to GNUradio. I am very much interested to work with it and to contribute something. As far as I have searched there is no DVB-S receiver module built for GNUradio but there were repos for DVB-S transmitter. Is there a reason

[Discuss-gnuradio] GRC file sink data types

Hi all, I am currently using the File Sink in GNUradio Companion by connecting a UHD USRP source to a File sink. By default, the UHD source block produces and output of "Complex Float 32". The File Sink has "Complex", "Float", "Int" available as input types. If I set the output of the UHD

Re: [Discuss-gnuradio] Serious bug in tag propagation with non-integer relative rate

I suppose if you don't have 64 bit, you can just shift it to be 32-bit and sacrifice the lost precision. There's probably other possibilities, but I think the newer ARM stuff is going 64-bit anyhow. On Mon, Nov 13, 2017 at 2:01 PM Marcus Müller wrote: > Ok, see your point. I

[Discuss-gnuradio] GSoC Ideas Page – please (for now) finalize!

Hey everyone, as Felix (in his position as GNU Radio GSoC manager) has been telling people through private channels over the last week, we're bringing our GSoC ideas list [1] up to shape, so that we can attract a lot of candidates, and make it easy for students to see how well they match the

Re: [Discuss-gnuradio] Serious bug in tag propagation with non-integer relative rate

Ok, see your point. I was a bit hesitant at first because that will end up needing 64bit division (which might really not be much fun on many ARMs), but meh, it's not like someone should be pushing tags around as if they're samples. Cheers, Marcus On Sun, 2017-11-12 at 23:33 +, Dan CaJacob

Re: [Discuss-gnuradio] reg:- sampling rate in GRC

Hello Rensi Sam: If you set the sampling rate of your hardware source/sink block to samp_rate, then it will generate or consume samples at that sampling rate. Ex: if the sampling rate of your Osmocom source block is set to 1e6, that block will generate 1e6 points per every second. In this case,

[Discuss-gnuradio] reg:- sampling rate in GRC

Hi I have a doubt regarding the sampling rate used in GNU radio. Is there any limit for the sampling rate (minimum/maximum) other than the Nyquist Criteria which should be used in GNU radio companion? Is there any difference  to the sampling rate (or limit to it) when we connect a hardware ?
