[Discuss-gnuradio] Ettus Research, Inc purchase by NI
The endeavors of the those I work with has involved applying serious research in SDR with the aid of people at Ettus and other GNURadio developers. We have applied serious funding to Ettus Research, Inc. in particular and GNURadio in general. We have every intention of continuing this and expanding it. We write GPL v3 code and we insist on the openness continuing. We have given code back to the repository for years and this will continue. A recent example is the new polyphase filter bank and arbitrary rate resampler code checked in by one of the developers for GNURadio. The amount of money and people time involved is significant to anyone's way of thinking and has directly impacted, in my view for the better, the quality and the quantity of the code currently in the repository. This too will continue. Companies, governments, scientists, engineers and even those that don't know it yet, NEED open source and open hardware and are supporting it and using it because of their need. Many in older stodgier communities have been slow to follow but are now really getting into the act. It is as simple as that. This trend will continue and you are seeing this trend reported about openly in various media. One needs only to decide to pay attention to see it. I would say for now, fear not, and congratulation to Matt. In my conversations with him, he feels that NI has left him in charge (he is the president of the new Ettus) and that while Ettus is a wholly owned subsidiary, it is not a small office inside the megalith of immovable bureaucracy. Ettus is a maker as are many of the rest of the developers in GNURadio. I think NI does not want to foul up what is working. In my mind, knowing something of Matt for years, he would not compromise his idealism for a buck. I have personal knowledge of at least one incident where he turned away enough money to satisfy dream's of avarice for most of us in a stand in defense of his idealism. I am proud to know him. The maker mentality's time has come and while USRP is not yet in the ideal "maker format" (no 3d printers are involved YET) it is moving that way with the inexpensive plug in cards. Hopefully you won't mind me plugging my favorite ex-EFF employee and favorite current syfy author's book on the subject. http://craphound.com/makers/makers_tor_big.jpg Bob (P.S.

[Discuss-gnuradio] RE: Ettus Research News.
I send this to Matt yesterday, but it really belongs in this forum: I wish I had known about the NI acquistion. I have seen this before. The company of some extraordinary contributors, the Zachman brothers, who wrote Hypersignal Ride DSP, was acquired by National Instruments in 2006. The availability of their product has dwindled, their initiative has been swallowed and they have disappeared from the DSP scene. As in - without a trace. Suppose you're a person interested in SDR. Click ni.com/labview. The barrier to entry is now extraordinarily high. The exact opposite of the Gnu model in hardware and software. I would be remiss if I did not mention this. That said, good luck to you in your endeavors. ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
[Discuss-gnuradio] GNU Radio support for Ettus Research USRP1/2
I'd like to clarify and respond to some concerns expressed about the software side of the GNU Radio/USRP SDR combination. First, we remain committed to maintaining Free Software Foundation copyrighted, GPLv3 licensed host code that provides the C++, Python and GNU Radio Companion interfaces to the USRP1 and USRP2 hardware within the GNU Radio framework. Today, this comes in two forms. The first is the two C++ "libusrp" and "libusrp2" shared libraries that provide low-level configuration and sample based access to the USRP hardware over their respective hardware interfaces. This is the kind of framework-independent driver code that is typically provided by hardware vendors and allows its use with a variety of software packages. Analogous drivers are the libasound driver for audio hardware or libhamlib for communication with various radios. Built on top of libusrp and libusrp2 are the GNU Radio gr-usrp and gr-usrp2 signal processing source and sink blocks. These provide the streaming signal flowgraph wrappers around libusrp(2) for C++ and Python applications, and the further metadata needed for use in the graphical design tool GRC. All the above are part of GNU Radio, are copyrighted by the FSF, are distributed in our software tarballs, source code repository, and binary packages, and are licensed for use and redistribution using the GPLv3. This code, with some further integration of the some in-progress development, will become part of our 3.3.x stable series, and will be maintained with bug fixes and/or updates should they become necessary. Ettus Research has announced their intent to release a "Universal Hardware Driver", or UHD, that will be a single driver approach to current and future hardware from them, and has also stated the UHD will be available under both GPL and non-GPL licenses. The UHD will perform essentially the same functions that libusrp and libusrp2 do now, and we will be able to have GNU Radio "gr-uhd" source and sink blocks to allow use within GNU Radio applications. This is a good thing for GNU Radio users for a variety of reasons: * It has proven tedious to develop GNU Radio applications that can transparently use either the USRP1 or USRP2. The UHD will abstract these differences so applications can adapt to the available hardware capabilities that are found. Currently we have some inelegant code to accomplish this but it's not an effective solution. * Future products from Ettus Research will get GNU Radio software support much more rapidly than in the past, as most of the differences will have already been addressed in the UHD. * The UHD makes it easier to expand support for the USRP into other, non-GNU Radio, frameworks or development environments. We see this as a good thing--it both promotes the use of low-cost SDR technology in general and provides an easier transition between those environments and GNU Radio. We have already been collaborating with Ettus Research for some time on the overall design of the UHD to ensure continuity of features and capabilities between the current GNU Radio libusrp(2)/gr-usrp(2) modules and the future Ettus Research UHD/GNU Radio gr-uhd modules supporting their hardware. While this intentionally won't extend to source code compatibility, we do think it will be straightforward to port applications. In addition, we will be coordinating distribution, installation, and maintenance of the software to keep things synchronized between the projects. The acquisition of Ettus Research by National Instruments is clearly recognition that the use of low-cost SDR hardware and open source SDR software has gained acceptance and use across a broad spectrum of academic, corporate, and government users. While it hasn't been explored in detail, there is also an opportunity to bring GNU Radio support to other NI products. It's an exciting time.

[Discuss-gnuradio] amplitude of gaussian noise (complex) - which one ?
given a gaussian distribution such as: with *zero mean*, which parameter of the function does the amplitude of this block represent ? sigma, sigma^2 , or the whole amplitude before the exponential term (so the variance is always 1) ? I ask you because i didn't find any hint in the documentation. thx in advance for the answer ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio

This is scary, but there are also some possibilities involved here too. This will give Matt more resources, which can benefit us if used correctly. And I guess nobody can turn down the possibility of making a couple of million bucks. I have always told NI people (including the local CEO) that their software and hardware sucks, because it is expensive, restrictive and runs well only on windows. We have bought hardware from NI for over ten times the price of a USRP and we still use USRP because it simply works better for us in terms flexibility and ease of use. Here is my wish list: 1. Maintain hackability of the hardware, keep the schematics open. And please, don't require proprietary rack mounting connectors. 2. Try to maintain the community. 3. And please, don't require me to find my latest NI update cds and serial numbers for my labview. I have no idea where they are. 4. Matt, please don't turn into a NI sales droid, at least not for another 10-20 years. juha ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
[Discuss-gnuradio] Data transfer using Sound cards
Hi All I am a beginner to the GNU Radio world ...so i apologize ahead if i am taking much of your precious time. I am trying to transfer data between two PCs running Ubuntu9.04 gnuradio 3.2.2 using a wired channel via sound cards.Looking in the mail list archive i found a similar topic but with no replies. My target is to implement an OFDM Transceiver over wired channel using gnuradio (ADSL modem).At this time i managed to send signals through the sound card using NBFM Transmitter but i can't acquire any Rx signal at the destenation PC Line in. I need to know how to deal with sound cards to be able to exchange data between the source and destination.

Re: [Discuss-gnuradio] Ettus Research News
Hi, I want to share my 2 cents: 1) Congratulation Matt. 2) Matt (and Ettus Research) has gave much to SDR open source community and deserve more funding. 3) May be things (for gnuradio community) will not be as it was before NI announcement, but one should not be selfish and let others who served (and still serving) the humanity with this great project (Eric, Johnathan, Matt, Josh, Tom,, etc) to take little financial benefits from their work. 4) We should be very grateful for them for sharing their knowledge with us and providing a low cost educational and business hardware/software platforms. 5) This is natural business development and I support the one who says that the resistance to this movement reveals a secret agenda. 6) I agree with the one who says it is business, but with my respect to him we do this business (in open source community) with friendship, fun and pleasure. Dear Matt, What is important to us is to keep providing the SDR hardware at lowest possible prices and keep developing your products. Congratulation again.
