[Discuss-gnuradio] Can one USRP be connected with multiple GNU Radio?
Hello, Can one USRP connected with multiple PCs, each of PC runs a GNU Radio, so as to formulate a distributed system? And on the other side, can one PC running GNU Radio be connected with multiple USRP?

回复: [Discuss-gnuradio] May I use GUN Radio without USRP
Hi, Josh Thank you very much, your opinion is really helpful! Yes, GNURadio + USRP is an excellent simulation environment. I will consider again how to leverage it for my application.

Gnuradio can be a stand-alone simulation environment. And you can interface it with anything that you can write code for. GNU Radio is... * An API for creating signal blocks (C++/Python) * A runtime environment for signal processing * A library of signal processing blocks * User scripts and applications * Hardware drivers (USRP/USRP2) * An application for creating flow graphs (GRC) > I mean Since USRP is just used for transiver, ADC/DAC, converting RF signal to > baseband and transmitting baseband signal to GNU Radio for processing, then may > I produce baseband workload by an Agilent baseband signal generator or even > Matlab, and then connect GNU Radio with signal generator or Matlab? > If you can write code in some language to acquire samples from lab equipment, then you can write a custom gnuradio block for that equipment. :-) > > The reason I am thinking about this is that from some analysis, I find the data > rate of the USB2.0 bus limits the bandwidth of the base band signal to 8 MHz, > which is not enough for my project.

Its usually a good idea to see that 1) you can implement the processing in simulation in the gnuradio environment 2) you can run the processing at a low rate on a platform like the USRP 2a) prove that the CPU can keep up at lower rates 2b) prove that the algorithm works in the presence of noise and frequency offsets So usrp can be a valuable part of your RF development even if you must replace it with a higher rate/more expensive device for delivery. Is the extra time spent integrating agilent equipment worth it if you find out that your algorithm cant run in real-time at lower usrp rates? Hope that helps! -Josh ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
[Discuss-gnuradio] May I use GUN Radio without USRP
Hello, I want to know may I use GNU radio without USRP. I mean Since USRP is just used for transiver, ADC/DAC, converting RF signal to baseband and transmitting baseband signal to GNU Radio for processing, then may I produce baseband workload by an Agilent baseband signal generator or even Matlab, and then connect GNU Radio with signal generator or Matlab? The reason I am thinking about this is that from some analysis, I find the data rate of the USB2.0 bus limits the bandwidth of the base band signal to 8 MHz, which is not enough for my project. And My focus is just baseband signal processing, I want to save money on USRP if I can use existing equipments in the lab.

RE: [Discuss-gnuradio] Can GNU Radio run on TI DSP environment?
That's really cool if Linux can run on TI multi-core DSP TMS320C6474! Where can I get this factory Linux, I don't find it at TI's website. Should I ask TI guys for it? Thanks!

It's a big deal for TI -- they should have had a factory Linux 10 years ago, but for whatever reasons they were way late to join the crowd. -Jeff > > 发件人: Jeff Brower > 收件人: Hanks > 抄 送: discuss-gnuradio@gnu.org > 发送日期: 2010/7/9 (周五) 6:41:05 下午 > 主 题: Re: [Discuss-gnuradio] Can GNU Radio run on TI DSP environment? > > Hanks- > >> I am new to GNU Radio.

Thanks! For the native, factory Linux running on their DSP cores, do you mean DSP/BIOS real-time OS?

If it can, how can I do it? As a starting point, look here: http://beagleboard.org/ In this case GNU radio runs on the ARM core side of an OMAP 3530 device (not on the DSP core). OMAP 3xxx devices can be found in some smart phones, for example Mot Droid and Palm Pre. Another area to look into is TI's recent announcment for a native, factory Linux running on their DSP cores, for example 6-core C6474 device. I have not heard of a GNU radio port (or any other popular open source sw, such as Asterisk) but I'm sure people are working on it. -Jeff ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio

Hello, I am new to GNU Radio. Currently I am considering to implement basic software radio and signal processing on TI DSP environment, such as TI TMS320C674x and C647x DSPs and the evaluation boards. I know GNU radio are usually running on PC environments for Linux or Window OS, but can it also run on TI DSP? If it can, how can I do it?
