A Technique to Enhance Localization in the Presence of NLOS Errors
— In a wireless network (WN), the wireless devices generally localize themselves with the help of anchors that are pre-deployed in the network. Some of the techniques commonly us...

Multiple-antenna multiple-relay system with precoding for multiuser transmission
Multi-hop relaying will play a central role in next generation wireless systems. In this paper a novel relaying strategy that uses multiple-input multiple-output (MIMO) relays in ...

Testing juntas nearly optimally
A function on n variables is called a k-junta if it depends on at most k of its variables. In this article, we show that it is possible to test whether a function is a k-junta or ...
