C02: Advances in signal processing for cognitive radio (2)

Monday, August 18  09:40-10:40,  Room #20

Cognitive radio has emerged as one of the most promising paradigms for efficient utilization of the radio spectrum. Still, a number of functions that any cognitive radio terminal has to accomplish are the subject of intense research. We think of spectrum sensing, of signal feature recognition, of the different criteria to authorize the use of the available bandwidth, and of the (dynamic) signal design criteria to optimize the exploitation of the spectrum resources. The session will also discuss particular criteria to design cognitive terminals, like software-defined or flexible radio.
