Performance Gains of Opportunism in Wireless Communications
Murat Torlak


Abstract: Traditional wireless communication theory views channel fading (channel fluctuations) as a problem to be mitigated. Recent developments in information theory suggest an alternative view: the channel fluctuations of the users can be exploited by means of multiuser diversity where the user transmissions are opportunistically scheduled when they experience a avorable SNR.  When channel fading is slow, multiple antenna transmitter is used to induce artificial temporal fading to ensure multiuser diversity in the network.  In the first part of my talk, I will present our theoretical and experimental work in opportunistic wireless communications. In the second part, I will present current opportunities at UT Dallas for research collaboration and student/faculty exchange.
