Interference-limited opportunistic relaying with reactive sensing
This work evaluates opportunistic relaying in the presence of thermal noise as well as interference, when channel sensing is conducted reactively, in slow fading environments. The ...

On Scaling Laws of Diversity Schemes in Decentralized Estimation
This paper is concerned with decentralized estimation of a Gaussian source using multiple sensors. We consider a diversity scheme where only the sensor with the best channel sends...
