All publications listed on this page are authored by one or more members of the Wireless Lab. Each publication contains theoretical formulations, optimization, and/or mathematical models, but several publications listed below are more experimental in nature than others, often involving actual hardware and real-world measurements. To distinguish these publications having significant experimental components, next to its title will be the badge Experimental. Those without such a badge can therefore be assumed to be more theoretical in nature, often validated purely using simulation as appropriate.
