Welcome to Wikipedia, Apinsaikeow! I am N2e and have been editing Wikipedia for quite some time. I just wanted to say hi and welcome you to Wikipedia! If you have any questions check out Wikipedia:Questions, or feel free to leave me a message on my talk page or type {{helpme}} at the bottom of this page. I love to help new users, so don't be afraid to leave a message! I hope you like the place and decide to stay. Here are some pages that you might find helpful:

- How to write a great article
I hope you enjoy editing here and being a Wikipedian! Also, when you post on talk pages you should sign your name using four tildes (~~~~); that should automatically produce your username and the date after your post. Again, welcome!
Cognitive Radio Technology
editApinsaikeow, you might find the following announcement of interest to your semester project. It would appear that perhaps "Cognitive Radio Technology" might provide an interesting counterpoint to your Spectrum auctions project; that is to say, this Cognitive Radio Technology might provide an alternative method by which additional electromagnetic spectrum might be obtained, and thus provide (pricing) information to spectrum bidders as to how the spectrum for sale might be valued by the market.

ITP Special Colloquium
Cognitive Radio Technology
Dr. David E. Borth 12:30pm Friday, February 25, 2011 CU Engineering Center, Onizuka Conference Room
Abstract:
In President Obama's recent State of the Union address, the President called for a National Wireless Initiative that would provide broadband wireless access to at least 98% of the American population. In order to achieve this task the President has set the goal of freeing up 500 MHz of spectrum for everything from smartphones to wireless broadband connectivity. The latter goal is consistent with the FCC's National Broadband Plan issued in March 2010. Yet to those that have studied the NTIA's chart of U.S. frequency allocations from 3 kHz to 300 GHz, it appears that the entire spectrum already has been allocated. One proposed solution to the spectrum crunch is to apply cognitive radio technology to new wireless systems going forward.
Cognitive radio is a method of coupling software-defined radio technology with a higher level "cognition" process that is able to sense when spectrum is available and then temporarily make use of that spectrum for communications. The origins of cognitive radio technology stem from early DARPA work but this technology has also been applied recently to TV white space devices. This presentation reviews some of the early work on cognitive radio technology and examines a number of the research technology challenges that need to be solved in order to deploy this technology broadly, including using this technology to solve the aforementioned spectrum challenge laid out by the President and the FCC. Some of these open issues include spectrum sensing, cooperative sensing, signal identification and retrofitting to existing wireless communication systems. In addition to the technology challenges associated with cognitive radio, there are also a number of other issues that need to be considered in any commercial deployment application including security issues. The presentation concludes with a look at needed policy and regulatory changes in order to deploy cognitive radio technology.
