The Gaussian Interference Relay Channel with a Potent Relay
—We consider the Gaussian interference channel with an intermediate relay. The relay is assumed to have abundant power and is named potent for that reason. A main reason to consi...

A Rate-Adaptive MAC Protocol for Low-Power Ultra-Wide Band Ad-Hoc Networks
Recent theoretical results show that it is optimal to allow interfering sources to transmit simultaneously as long as they are outside a well-defined exclusion region around a de...

Code design for MIMO downlink with imperfect CSIT
—In this letter, we implement a simplified version of the Cover - van der Meulen - Hajek - Pursley (CMHP) coding originally characterized by Wajcer, Wiesel, and Shamai. The vect...
