Estimation of space-time varying channels using signal subspace projection and soft information
We consider the uplink of a time-slotted wireless communication system with a mobile user and a base station equipped with an antenna array of

Ultra-fast tracking based on zero-shift points
A novel tracker based on points where the intensity function is locally even is presented. Tracking of these so called zeroshift points (ZSPs) is very efficient, a single point i...

Characterizing physical-layer secrecy with unknown eavesdropper locations and channels
—We present a probabilistic framework for physical layer secrecy when the locations and channels of the eavesdroppers are unknown. The locations are modeled by a Poisson point pr...
