Transmission Schemes for Multicarrier Broadcast and Unicast Hybrid Systems
Abstract--Wireless infrastructures can be conveniently categorized into two types: those that provide point-to-point `unicast' connectivity (e.g., cellular) and others that ar...

Asymptotically optimal time synchronization in dense sensor networks
We consider the problem of synchronization of all clocks in a sensor network, in the regime of asymptotically high node densities. We formulate this problem as one in which all cl...

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 ...
