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...

Normal Proofs in Intruder Theories
Given an arbitrary intruder deduction capability, modeled as an inference system S and a protocol, we show how to compute an inference system bS such that the security problem for ...

A Feedback Reduction Technique for MIMO Broadcast Channels
A multiple antenna broadcast channel with perfect channel state information at the receivers is considered. If each receiver quantizes its channel knowledge to a finite number of b...

A numerical algorithm for zero counting, I: Complexity and accuracy
We describe an algorithm to count the number of distinct real zeros of a polynomial (square) system f. The algorithm performs O(log(nD(f))) iterations (grid refinements) where n is...
