[Discuss-gnuradio] How to change the SNR through gnuradio

Hi, I want to change the SNR through gnuradio.Can I realize it by just change the gain of the gnuradio?Or the instrument is fixed,and the snr can't be change? Thanks so much. Best Regards, zs ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.

Re: [Discuss-gnuradio] Saving Waterfall to Video File

In the past, I have saved decimated vectors of the signal to a file and used that to recreate a long, static waterfall plot for debug of satellite passes. On Sun, Feb 28, 2016 at 2:19 PM Stephen Berger < stephen.berger.temconsult...@gmail.com> wrote: > I would like to save a waterfall plot (spect

Everyone, I'm really happy to say that GNU Radio was accepted as a participating organization for Google Summer of Code 2016! After not participating last year, I'm very glad I can give this news, and it'll be the fourth time that we participate in this program. Note: We'll also apply for SOCIS ag

Re: [Discuss-gnuradio] Is there way to specify the destination of signal ?

Dear SangHyuk Kim, Yes, that's possible, but the way you describe this is a Layer 2 or even Layer 3 problem – the typical job of GNU Radio is to do signal processing, i.e. Layer 1. Of course, as Basti's gr-ieee802-11 demonstrates, you can write very practical blocks that doe the MAC logic; but tha

Hi all. I want to make unicast communication system such as Wi-Fi using SDR(in my case, usrp n210) however, I can't find any block like of that. Exactly what I'm saying like this situation : A ---> B C (A; Tx packet to B, B; Rx packet from A, C; discard packet from A to B) Is this po

Re: [Discuss-gnuradio] Using volk kernels on basic operations of gr_complex, in my own custom blocks.

It won't give you time spent, but 'perf top' is a nice tool that gives function-level performance counters for all running code. It comes with linux-tools and uses performance counters built in to the kernel. There's also a couple of other perf subtools you can explore. Regarding your full buffer
