Communication theory is one of the few in engineering that actually has a set of known, computable boundaries for optimum system performance, which boundaries serve [...]

Today, the FCC announced the rules governing the use of unlicensed devices in TV white spaces will officially go into effect Jan. 5, 2011. FCC [...]

In some outposts of the wireless engineering community, “cognitive radio” (CR) and “software defined radio” (SDR) are sub-disciplines used in common practice, just like “artificial [...]

We have been hearing so much about Cognitive Radio (CR) technology, we wondered if it really is a significant research topic. Is CR anything more [...]

Nokia has produced a really cool animation about CR that can be enjoyed by everyone, even a policy maker. Thanks to Ozzie Diaz of Air [...]

On 2-25-10 we moderated a panel session of the Cognitive Radio Special Interest Group within the Wireless Communications Alliance. WCA is a Silicon Valley based [...]

It is notable that two major news outlets have featured Cognitive Radio very recently. First, EE Times has a great piece in conjunction with the [...]

Cognitive Radio architectures and implementations require advanced signal processing. While the algorithms can be implemented in software, of course, the ability for RF systems to [...]

Anthropomorphizing about spectrum or information is pretty catchy, but weird. But maybe Google is even weirder when it offers to fund the creation and use of [...]

The FCC wants to get substantially better use of spectrum, and they advocate using economic principles of competition to guide allocations. Only by using Cognitive [...]
