Approximately counting integral flows and cell-bounded contingency tables
We consider the problem of approximately counting integral flows in a network. We show that there is an fpras based on volume estimation if all capacities are sufficiently large, ...

Solvability in Resource Lambda-Calculus
Abstract. The resource calculus is an extension of the λ-calculus allowing to model resource consumption. Namely, the argument of a function comes as a finite multiset of resourc...

An Efficient Criterion for Mode Decision in H.264/AVC
In this paper, an efficient cost function for mode decision in H.264/AVC is proposed. The proposed cost function is based on integer transform coefficients, where the rate and the...

Adaptive Mode Selection for Multiuser MIMO Downlink Systems
This paper proposes a block diagonalization (BD) method, which nullifies the multiuser interference and, hence, increases the sum capacity in a multiuser multiple-input multipleout...

Low complexity equalization for doubly selective channels modeled by a basis expansion
We propose a novel equalization method for doubly selective wireless channels, whose taps are represented by an arbitrary Basis Expansion Model (BEM). We view such a channel in the...
