On the efficiency of transmission strategies for broadcast channels using finite size constellations
Zeina Mheich, Florence Alberge, Pierre Duhamel
In this paper, achievable rates regions are derived for power constrained Gaussian broadcast channel of two users using finite dimension constellations. Various transmission strate…
New Criteria for Iterative Decoding
Florence Alberge, Ziad Naja, P. Duhamel
Iterative decoding was not originally introduced as the solution to an optimization problem rendering the analysis of its convergence very difficult. In this paper, we investigate…
Geometrical interpretation and improvements of the Blahut-Arimoto's algorithm
Ziad Naja, Florence Alberge, P. Duhamel
The paper first recalls the Blahut Arimoto algorithm for computing the capacity of arbitrary discrete memoryless channels, as an example of an iterative algorithm working with prob…
Méthode du point proximal: principe et applications aux algorithmes itératifs
Ziad Naja, Florence Alberge, P. Duhamel
This paper recalls the proximal point method. We study two iterative algorithms: the Blahut-Arimoto algorithm for computing the capacity of arbitrary discrete memoryless channels,…
