Re: [Discuss-gnuradio] ISDB-T Modulation?

Hi Jordan, I remember a group from Brasil presenting a ISDB-T modulator implemented in gnuradio when I attended wireless innovation forum in 2012. The presentation is here: http://groups.winnforum.org/europe_papers_wednesday#2.3, A Software Defined Radio Approach for Digital Television ISDB-T T

Re: [Discuss-gnuradio] ISDB-T Modulation?

Hi Jordan, I live in Brazil and I always tried to find efforts developing an ISDB-T modulator, but never find it. Of course it'll not be a from-scratch effort, as some blocks are already in gnuradio. Best regards, Rafael Diniz > I am aware that ATSC, and various forms of DVB-T/2 modulators exist

Re: [Discuss-gnuradio] Sending/Receiving UDP Data Over Internet

The error you are getting is possibly due to your host machine using a LAN address to access the internet via NAT (network address translation). If this is the case then setting your receive ip address to '0.0.0.0' in the GRC 'UDP Source' should do the trick. This setting tells the 'UDP Source' t

[Discuss-gnuradio] ISDB-T Modulation?

I am aware that ATSC, and various forms of DVB-T/2 modulators exist in GNURadio both with standard and custom blocks; but is there any active development or possibility of ISDB-T modulation? What exactly would need to be done in order to achieve it? It doesn't seem all-too different from DVB-T in t

Re: [Discuss-gnuradio] Sending/Receiving UDP Data Over Internet

Hi Matias, usually, binding ports over 9000 should be possible for normal users, but if you already made sure that your address is correct and there is nothing else occupying port 9000, I'd check with the Ubuntu folks if there is something like seLinux blocking such things. As a side note, never e

Hello, We would like to send UDP data from a USRP over the internet to a remote computer. The setup on the host side is: USRP Source --> UDP Sink And on the client side: UDP Source --> Throttle --> WX GUI FFT Sink This setup has worked on a local network using the client's IP address "10.10.0.

Re: [Discuss-gnuradio] Writing new block or editing existing block in Gnuradio Companion Windows

Hi Sun, GNU Radio does not really care about your OS; unless you want to do something OS-specific, the source code is all the same. Also, 3.6.4 is obsolete; update to 3.7.4 if possible. Greetings, Marcus On 23.06.2014 11:28, Sun Wenbin wrote: > Greetings everyone, > My sincere apologies in adva
