Block-Floating-Point Enhanced MMSE Filter Matrix Computation for MIMO-OFDM Communication Systems

Andreas Peter Burg, Carl Christian Sten Dominic Senning

n this paper we present an architecture for an MMSE ﬁlter matrix computation unit for signal detection in MIMO-OFDM communication systems. We propose to compute the required matrix inverse based on a Cholesky decomposition, followed by a Gauss-Jordan matri ...

On the non-stiffness of edge transport in L-modes

Olivier Sauter, Basil Duval, Stefano Coda, Timothy Goodman, Stephan Brunner, Alexander Karpushov, Antoine Pierre Emmanuel Alexis Merle, Yann Camenen, Roland Behn, Doohyun Kim, Gabriele Merlo, Lucia Isabel Federspiel

Transport analyses using first principle turbulence codes as well as 1½-D transport codes often study transport properties between the plasma axis and a normalized radius around 0.8. In this region, heat transport shows significant stiffness properties lea ...

Affine Processes On Positive Semidefinite Matrices

Damir Filipovic

This article provides the mathematical foundation for stochastically continuous affine processes on the cone of positive semidefinite symmetric matrices. This analysis has been motivated by a large and growing use of matrix-valued affine processes in finan ...

Polar Codes: Characterization of Exponent, Bounds, and Constructions

Rüdiger Urbanke, Satish Babu Korada, Eren Sasoglu

Polar codes were recently introduced by Arikan. They achieve the capacity of arbitrary symmetric binary-input discrete memoryless channels under a low complexity successive cancellation decoding strategy. The original polar code construction is closely rel ...

Block variants of Hammarling's method for solving Lyapunov equations

Daniel Kressner

This article is concerned with the efficient numerical solution of the Lyapunov equation A(T) X + XA = -C with a stable matrix A and a symmetric positive semidefinite matrix C of possibly small rank. We discuss the efficient implementation of Hammarling's ...

Étude du transport d'énergie thermique dans les plasmas du tokamak à configuration variable au moyen de chauffage électronique cyclotronique

Yann Camenen

The development of controlled thermonuclear fusion, a quasi-unlimited energy source suitable for large scale electricity production, is one of the main goals of plasma physics research. Among the directions explored to date, the use of toroidal devices cal ...

Electron heat transport in shaped TCV L-mode plasmas

Olivier Sauter, Stefano Coda, Timothy Goodman, Laurie Porte, Alexander Karpushov, Antoine Pochelon, Yann Camenen, Roland Behn, Alberto Bottino

Electron heat transport experiments are performed in L-mode discharges at various plasma triangularities, using radially localized electron cyclotron heating to vary independently both the electron temperature T-e and the normalized electron temperature gr ...

The Degenerate Bounded Errors-in-Variables Model

Ali H. Sayed

We consider the following problem:

\min_{x \in {\cal R}^n} \min_{\|E\| \le \eta} \|(A+E)x-b\|

, where A is an

m \times n

real matrix and b is an n-dimensional real column vector when it has multiple global minima. This problem is an errors-in-variables ...
