Link Adaptation in Linearly Precoded Closed-Loop MIMO-OFDM Systems with Linear Receivers
Abstract--Upcoming multi antenna systems such as 3GPPLTE employ code book based multi-mode precoding in order to adapt to a wide range of channel conditions. Link adaptation, which...

Effectively inseparable Boolean algebras in lattices of sentences
We show the non-arithmeticity of 1st order theories of lattices of n sentences modulo provable equivalence in a formal theory, of diagonalizable algebras of a wider class of arithm...

The Inverse Taylor Expansion Problem in Linear Logic
Linear Logic is based on the analogy between algebraic linearity (i.e. commutation with sums and scalar products) and the computer science linearity (i.e. calling inputs only once...

An algebraic multigrid solver for analytical placement with layout based clustering
An efficient matrix solver is critical to the analytical placement. As the size of the matrix becomes huge, the multilevel methods turn out to be more efficient and more scalable....

Rewriting Variables: The Complexity of Fast Algebraic Attacks on Stream Ciphers
Recently proposed algebraic attacks [2, 6] and fast algebraic attacks [1, 5] have provided the best analyses against some deployed LFSR-based ciphers. The process complexity is exp...
