At the Wireless Innovation Forum (formerly SDR Forum) meeting in Mainz, Germany from June 21-23 (link), I’m trying to pull together a session of presentations on the funded EU-area research initiatives on Cognitive Radio and Cognitive Radio related technologies.
The intent is to provide a mechanism for the different groups to share with one another what they’re doing and to help spur research collaborations among the groups and to expose the research efforts to the companies that attend the Forum meeting.
Each group would be given 20 minutes a piece to overview their group’s efforts (I’m really flexible on what can appear in the slides as it’s kinda your time at that point).
If a group can’t attend in person, but would still like their activities highlighted in the session, I’m willing to present any material that’s submitted in the session assuming I can follow the slides. [obviously, you know your research better than I do, so this is suboptimal, but still preferable to nothing]
If we get more interest than can be accommodated in a single session, I’ll try to add time or an extra session. If I can’t extend the session or add another session, then I’ll give first preference to those universities / groups that are members of the Forum and then to those that can be there in person and finally to the rest in a completely unfair, arbitrary, and caprcious manner of my choosing [actually probably via a uniform random number generator, but I like to head off issues preemptively by embracing potential complaints].
Any slides presented would need to be releasable as they’ll be posted on the Forum’s meeting dropbox for all of the Forum members to access.
I’ll send out a formal email invitation next week (this is a kind of advance notice for those in the EU CR community that read this blog), and I think I know who to email for most of the groups, but if you want to make certain I catch you in the announcement, send me an email at

This is kinda old but I’m putting up stuff while I’m sitting through the WinnForum plenaries…
(link) Key material from the release.
The Communications-Electronics Research, Development and Engineering Center (CERDEC) is creating a Software-Defined Radio lab that will work with the Navy Research Lab to transfer work done previously on the Joint Tactical Radio System to the GNU Radio’s open-source, free software environment.
Tim Leising, director of the Software-Defined Radio lab at CERDEC, said his group is focusing on developing and testing future software defined radios with the GNU platform to promote collaboration and information-sharing via network connections.
Upshot - some more efforts behind open source CR. Cheaper radios also allows for more cognitive networking kinds of work.

1900.4 (Architecture)
- Three use cases:
- dynamic spectrum assignment, dynamic spectrum sharing, distributed radio resource usage optimization (considers heterogeneous networks)
- Architecture consists of terminal and network with terminal reconfiguration manager, controller and collector. Network has similar parts but with operator spectrum manager. Both sides work together to effect reconfigurations.
1900.4a interfaces for DSA in TVWS; updated system functional archs
Status: draft almost ready. Ballot to start in April
1900.4.1 Interfaces and protocols for distributed decision making for optimize RRM in heterogeneous wireless nets.
Status: Draft in development. Still with a call for contributions.
In effect these two (1900.4a, 1900.4.1) specify the comm between the TRM and NRM
1900.5 (Policy languages)
Status: Liasion wiht 1900.4; Formal MOU with WinnForum MLM (Meta-Language for Mobility). Draft standard in progress. Much more work required
1900.6 (datastructure and interface for spectrum sensing)
Architecture views sensors managed by one or more cognitive engines, possibly co-located
Status: Resolbed all 131 comments. Initial draft for sponsor ballot was approved. Move to readiness review.
New Business
New standard proposal - white space radio interface standard based on SCC41
Next PLenary July 6-9 in Delft.
1900.4, 6 on May 25-27 in Okinawa Japan

(link, doc) Yesterday, the Defense Information Systems Agency (DISA) posted a BAA (BAA-DSO-10-01) on analytic spectrum studies of DSA networks. The link is to the FBO page, the doc to the solicitation. More specifically, they appear to be looking for guidance on how to manage spectrum in a DSA world and want an architecture for how to do this. Excerpting the key part of the solicitation from the document…
and capable of performing analytical spectrum studies of DSA networks. The areas of focus for Proposal abstracts and Proposals submitted in response to this BAA as follows:
The proposal should focus on developing system architectures for DSA networks, with a particular emphasis on their application to policy-based management system architecture that is integrated with the Global Information Grid (GiG). The proposal should address one or more of (but is not limited to) the following areas: (1) develop scalable and federated policy-based management system architectures that can effectively and efficiently manage DSA radios across the battlespace. The system architecture should address spectrum management, network management, and security; (2) develop system architectures that enable automated request, control, exchanges, cross domain automated policy negotiation, and negotiation between systems in different networks and security domains in support of coalition partners and provide deconfliction with EW devices based on real-time battlefield needs, (3) Address interface requirements of selecting spectrum planning tools and gateway between ground, sea, air and space networks in support of DoD, coalition forces, and other government agencies; (4) Conduct a trade-off study of centralized versus distributed policy-based management system architecture.
The architecture deliverable should be compliant with the DoD Architecture Framework, Version 2.0. In addition, it is important that the incumbent be knowledgeable of the Defense Spectrum Management Architecture (DSMA), as this architectural product will ultimately either be subsumed within or federated with the DSMA.
Full proposal response date is Mar 26, 2010. Abstracts are encouranged (but not required) to be submitted within 20 days of the BAA (Jan 26, 2010).

(link) (Response date Feb 4) AFRL Wright-Pat issued an RFI on Wednesday (Jan 20) seeking information on cogntiive jammers.
The Electronic Warfare Techniques Development and Analysis Branch of the Senors Directorate, Air Force Research Laboratory, WPAFB OH (AFRL/RYRE) is issuing a request for information (RFI) for new and innovative technologies, techniques, and concepts that will enable development and implementation of a first generation Cognitive Jammer (CJ) system. Candidate technologies/techniques/concepts will be considered for potential funding…
Traditionally countermeasures are categorized as either Radar or Communications. They have limited adaptability and are effective against a pre-determined or well exploited threat. The advent of Dynamic Spectrum Access (DSA) technologies such as Software Defined Radio (SDR) / Cognitive Radio and its proliferation further challenges the EW community. The objective of the CJ is to promote spectrum dominance by improving the jamming effectiveness while at the same time taking measures to minimize fratricide. CJ is envisioned as an adaptive, multifunctional (communications, radar, navigation and etc.), cross-layered jamming system based on a networked Software Defined Architecture (SDA). This RFI seeks ideas addressing each one of the current limitations and how to fill in those gaps.

Today’s the deadline for submitting papers and tutorial proposals for the 20th Annual Wireless @ VT Summer School and Symposium. It’ll be in Blacksburg June 2-4, 2010. Somewhat presumptively, I’ll be giving an updated version of my tutorial on emerging wireless standards, but with a focus on TV white space standards. You can see last year’s version (focused on LTE, but had the most discussions on WiMAX) @ this link and the abstract for the tutorial in the full post. Read the rest of this entry »

Posted in Ham, research initiatives at 8:47 am by jody
(link) Tennessee Tech has a $800k CR project starting.
Congressman Bart Gordon has announced that he was able to secure funding for Tennessee Tech University to help design innovative radios for military use. TTU’s Cognitive Radio Institute will receive $800,000, which will be used to design radio experimental models and system test-beds that are resistant to conventional jamming techniques.
I think this is the lab.
(link) “Government Controlled Radio” - This Ham doesn’t like where CR is heading (which is to allow CR in the Ham bands)
So a new STA is being prepared to study CR on the Ham bands. This may be a funded research project. Is it legal? Well an educational institution can use Ham radio and be paid. My reading was always that this exception was to teach Ham Radio licenses classes or basic radio technology. Maybe paid research should get its own frequencies and license?
But what’s in it for Ham Radio? A new co-user of our spectrum? Increased noise floor from the Spread Spectrum, SDR, and CR modes of operation? The end of spinning the dial and listening for a random CQ? If you are not transmitting the CR does not hear you and takes the band. If the QRM is at the DX end and the CR cannot hear other users what then? Maybe it will be smart enough to have the DX station inform it of local QRM? Pretty smart radio, eh?

Posted in Broadcast, White Space at 10:52 am by jody
From here (don’t interpret my use of “amusing” to imply wrong especially in light of the CTIA response to FCC Spectrum Innovation inquiry):
If license exempt white space devices are commercially successful, it will become increasingly difficult and then politically impossible for Congress or the FCC to recapture TV spectrum for exclusive use by the mobile industry. If Wi-Fi, WiMAX and other consumer devices appear using TV frequencies, it will become harder and harder to displace these consumer uses and recapture the exclusive use the mobile industry requires.
So, if the broadcast industry really wants to hold onto their current spectrum rights, they should get as many non-interfering “secondary users” into their band as possible. Otherwise, they will eventually lose their primary rights to the quest for more mobile broadband.
