The next meeting of the Ottawa Valley Mobile Radio Club will be on October 18th at the Science Museum in Ottawa
Today in my email I recieved this piece of information about the guest speaker/topic for the October Meeting and was asked to share it with you….

TITLE: Cognitive Radio Explained to the Radio Amateur
SPEAKER: Michel Barbeau, VE3EMB
ABSTRACT:
I am a reader of VA3QV’s blog. In a recent post entitled “Goodbye to an old friend” (August 24, 2012), Bob talks about its Yaesu FT897 that he just sold. As the name of the post suggests, it is as if Bob and the FT897 developed a friendship over time. This is pretty much what the cognitive radio concept is all about. It is a radio that can think. It has a sort of brain with memory and reasoning capability. It is able to sense the channel conditions, understand the operator’s preferences, use past experience and determine by itself how it should operate. After a while, it becomes a sort of operator’s good friend.
The cognitive radio paradigm has not yet penetrated the amateur radio market. There are, however, interesting upcoming applications we should keep an eye on. In the US, UHF spectrum previously allocated to television broadcast has been reallocated to wireless networks. The software defined radio technology will be used to make these networks adaptable and perform at their best. Besides, new interference management models between radio services are being investigated, such as the concept of interference temperature. The topic “cognitive radio system” was on the agenda of the last World Radiocommunication Conference (2012). Input have been solicited from the amateur radio community.
I will introduce this new concept and review some of the practical ideas that have been put forth. All are welcome!

Hope to CU there
