Multi-User Diversity vs. Accurate Channel Feedback for MIMO Broadcast Channels
— A multiple transmit antenna, single receive antenna (per receiver) downlink channel with limited channel feedback is considered. Given a constraint on the total system-wide cha...

Beamforming with Finite Rate Feedback for LOS MIMO Downlink Channels
— We consider a MIMO line of sight (LOS) broadcast channel where each user has perfect knowledge of its own channel and feeds back ‘quantized’ channel information to the tran...

Joint optimization of the redundancy of multiple-description coders for multicast
We consider the optimization of multicast over packet-switched communication networks with a non-zero packet-loss probability. For the system setup consisting of a number of multi...

Efficiently Certifying Non-Integer Powers
We describe a randomized algorithm that, given an integer a, produces a certificate that the integer is not a pure power of an integer in expected (log a)1+o(1) bit operations unde...

Model Checking Prioritized Timed Automata
Abstract. Priorities are often used to resolve conflicts in timed systems. However, priorities are not directly supported by state-of-art model checkers. Often, a designer has to ...
