Cooperative Communications with Outage-Optimal Opportunistic Relaying
TLDR
We show that opportunistic DaF relaying is outage-optimal, that is, it is equivalent in outage behavior to the optimal DaF strategy that employs all potential relays and significantly outperforms an AaF strategy based on equal-power multiple-relay transmissions with local channel knowledge. Expand

TLDR
In this paper, we characterize localization accuracy in terms of a performance measure called the squared position error bound (SPEB), and introduce the notion of equivalent Fisher information (EFI) to derive the SPEB in a succinct expression. Expand

The ultra-wide bandwidth indoor channel: from statistical model to simulations
TLDR
We establish a statistical model for the ultra-wide bandwidth (UWB) indoor channel based on an extensive measurement campaign in a typical modern office building with 2-ns delay resolution based on the statistical properties of the multipath profiles measured in different rooms over a finely spaced measurement grid.
