We consider compound multi-input multi-output (MIMO) wiretap channels where minimal channel state information at the transmitter (CSIT) is assumed. Code construction is given for the special case of isotropic mutual information, which serves as a con

The secrecy gain is a lattice invariant that appears in the context of wiretap lattice coding. It has been studied for unimodular lattices, for 2 −, 3 −, and 5 −modular lattices. This paper studies the secrecy gain for extremal even l-modular l

In this paper we present a new scheme combining artificial noise beam forming and secrecy coding to strengthen the security of existing wireless communication systems. Artificial noise and beam forming guarantee a radio advantage to legitimate users,

Previous approaches to compute-and-forward (C\&F) are mostly based on quantizing channel coefficients to integers. In this work, we investigate the C\&F strategy over block fading channels using Construction A over rings, so as to allow better quanti

International audience; Lattice codes used under the Compute-and-Forward paradigm suggest an alternative strategy for the standard Gaussian multiple-access channel (MAC). It has been proven that decoding an integer linear combination of the transmitt

Lattices from Construction A and non-binary codes are considered. These lattices are built from number fields as coset codes of the ring of integers O K modulo an ideal I. Diversity of a Construction-A lattice Λ on block-fading channels is guarantee

In this paper, we present a multidimensional trellis coded modulation scheme for a high rate 2times2 multiple-input multiple-output (MIMO) system over slow fading channels. Set partitioning of the Golden code is designed specifically to increase the

In this paper, we study the feasibility of the interference alignment (IA) scheme for the selective fading interference channel with time-frequency selective links. Unlike the frequency selective channel case, we show here that, for the scalar time-f

In this work we show that algebraic lattices con- structed from error-correcting codes achieve the ergodic capacity of the fading channel. The main ingredients for our construction are a generalized version of the Minkowski-Hlawka theorem and shaping

International audience; In this paper, we propose a multilevel lattice construction, employing binary Reed-Muller codes, for the Rayleigh block fading channel. The construction is performed on a binary two-dimensional lattice partition chain, and a c
