— We consider a wireless multiuser network where a number of source/destination pairs communicate concurrently over the same physical channel. A set of amplify-and-forward relay ...
Abstract--Spatial interference alignment among a finite number of users is investigated as a technique to increase the probability of successful transmission in an interference lim...
Recently, cooperative communication has attracted a lot of attention for its potential to increase spatial diversity. However, limited attention has been paid to the physical laye...
Abstract— This paper experimentally investigates the feasibility of crypto-free communications in resource-constrained wireless sensor networks. We exploit the spatial signature ...
Abstract— We consider the problem of determining the positions of wireless nodes using range measurements from multiple, sparsely located, beacon stations with known locations. A...
