The DTT device: Power and particle exhaust

Holger Reimerdes

The possible scenarios at full power of the DTT (Divertor Test Tokamak) device with the standard single null (SN) and X divertor (XD) configurations have been analysed for the aspect of safely handling the power to be exhausted on the divertor targets. In ...

LLR Compression for BICM Systems Using Large Constellations

Bixio Rimoldi, Stefano Rosati

Digital video broadcasting (DVB-C2) and other modern communication standards increase diversity by means of a symbol-level interleaver that spans over several codewords. Deinterleaving at the receiver requires a large memory, which has a significant impact ...

Fast and Robust Parametric Estimation of Jointly Sparse Channels

Martin Vetterli, Yann Barbotin

We consider the joint estimation of multipath channels obtained with a set of receiving antennas and uniformly probed in the frequency domain. This scenario fits most of the modern outdoor communication protocols for mobile access (ETSI Std. 125 913) or di ...

Where are we in understanding salamander locomotion: biological and robotic perspectives on kinematics

Auke Ijspeert, Konstantinos Karakasiliotis

Salamanders have captured the interest of biologists and roboticists for decades because of their ability to locomote in different environments and their resemblance to early representatives of tetrapods. In this article, we review biological and robotic s ...

Plasma Isotopic Effect on the Damping Rate of Toroidal Alfven Eigenmodes with Intermediate Toroidal Mode Numbers

Ambrogio Fasoli, Duccio Testa, Patrick Blanchard, Theodoros Panis

This paper reports on the results of recent experiments performed on the JET tokamak on toroidal Alfvén eigenmodes (TAEs) with toroidal mode number (n) in the range up to |n|=7. The stability properties of these medium-nTAEs are investigated experimentally ...

Optimal Spectral Feature Detection for Spectrum Sensing at Very Low SNR

Ali H. Sayed, Wenyi Zhang

Spectrum sensing is one of the enabling functionalities for cognitive radio systems to operate in the spectrum white space. To protect the primary incumbent users from interference, the cognitive radio is required to detect incumbent signals at very low si ...

A Novel Conflict-Free Memory and Processor Architecture for DVB-T2 LDPC Decoding

Alberto Jimenez Pacheco

In this paper, we present a flexible architecture for an LDPC decoder that fully exploits the structure of the codes defined in the DVB-T2 standard (Digital Video Broadcasting - Second Generation Terrestrial). We propose a processor and memory architecture ...
