Ergodic Secrecy Capacity Region of the Fading Broadcast Channel
— We consider the fading broadcast channel from a secrecy point of view. In this channel, each user views the other user as an eavesdropper, and wants to keep its information as ...

Transmit beamforming for wireless multicasting using channel orthogonalization and local refinement
The problem of transmit beamforming for single-group multicasting is considered, where the objective is to transmit common information to a (large) number of users. The transmitte...

Motion effect modeling in multipath configuration using warping based lag-Doppler filtering
The estimation of the impulse response (IR) of a propagation channel is necessary for a large number of acoustic applications: underwater communication, detection and localization...
