ECWS Presentations from 802 Plenary
While I wasn’t there , the March 802 Plenary had a major presentation from the ECWS (in fact it was the primary deliverable for the group.) Based on email traffic I’ve read, it looks unclear at this point in what form this will be continuing on as. [Update 3/16/09 – ECWS disbanded, coexistence work continues in 802.19 as a study group with the outputs of two documents “one on coexistence scenarios and one on coexistence mechanisms, with a plan for when the deliverables will be completed, with interim steps” (802.19 note from here and ECWS disbanding coming via email)]
Nonetheless, if you want to get up to speed on their activities, these two links will do a good job.
(pdf) Tutorial. Quite a large file (~ 7.25 MB), but lots of good information.
(ppt) ECWS Chair’s Report. (Just main takeaways from tutorial and much smaller)
(pdf) Spectrum Sharing in TV White Space Workshop.
As part of its June meeting in Detroit (June 15-18), the SDR Forum will host a workshop on coexistence of TV white space devices on June 16. They’re currently soliciting proposals for presentations through April 1.
(no link) Cognitive Radio and Intelligent Transportation Systems at SDRF ITS Workshop
Intelligent Transportation Systems effectively apply the concept of a cognitive system to the management of transportation systems (gather information, recognize patterns, apply rules / reason, learn from past actions). Wireless links play a big role in transferring information and control messages and cognitive radio can help improve the communications quality and availability in this highly dynamic environment. Once cognitive radio is integrated into and fielded with ITS, we’ll have “cognitive systems of cognitive systems”, which is one of the broader trends I see for the future.
As of this week, I’ll be giving a 30-minute talk with Ashwin Amana on cognitive radio and intelligent transportation systems at the SDR Forum ITS Workshop, also at the SDR Forum Detroit meeting (so many great workshops crammed into such a short meeting).
(link) IWCE Panel to Discuss Cognitive Radio
Really, it’s a panel to highlight NIJ’s communications related research efforts. But one of the major thrusts has been cognitive radio. Charles Bostian of VT will be discussing their NIJ-funded efforts to create the Public Safety Cognitive Radio (PSCR) node. IWCE is March 16-20 (Vegas), and the panel is on March 18th, from 1:30-2:45 PM.
(link) EMC Electronica article on embedded SDR and CR.
Not the most illuminating article, but it does note the natural relationship between SDR and CR (though very DSA focused) and the role of embedded processing in realizing CR. Really, this is just an excuse to note that CRT is currently executing a SBIR to realize embedded cognitive spectrum management on JTRS radios (JTRS defines a DoD standard for SDR platforms). (pdf of a flyer we pass out on the topic)
(link) New CR Blog
I don’t know who he is, but James (not me) is posting his notes on his “4th year project on cognitive radio” as it progresses. At least so far, he’s doing a good job of capturing and linking to important papers.
