Statut de la littérature et science-fiction by Cédric Chauvin

“…Il ne s’agit pas, ici, d’effacer les différences, mais plutôt de voir comment plusieurs auteurs de science-fiction, de moments historiques et d’ancrages contextuels divers, se positionnent vis-à-vis des définitions de la littérature qui leur sont contemporaines : lisant des textes de Jules Verne, de Stanislas Lem et de Greg Egan, nous émettrons l’hypothèse que ce positionnement, dans les œuvres de science-fiction et au sein de leur cadre spécifique, permet, comme à distance, une mise en jeu critique des questions propres aux littératures dominantes de leurs temps respectifs.…”

Joint symbol detection and channel estimation for MIMO-OFDM systems via the variational Bayes EM algorithm by ZHANG Xiao-ying, WEI Ji-bo, WANG De-gang, XIONG Chun-lin

“…A new joint symbol detection and channel estimation algorithm was proposed for MIMO-OFDM systems over the time-varying fading channel based on the variational Bayes expectation maximization algorithm and Turbo principle.The channel estimation error covariance matrix was considered in the soft-input soft-output detector which circumvented the undesirable exhaustive search via list sphere decoder（LSD）.In addition,a novel Kalman forward-backward channel estimator was derived based on the posterior distributions of the transmitted symbols which were obtained from the space-time detection.Simulation results show that the proposed algorithm has more robust performance than the conven-tional EM algorithm and decision-directed technique in the time varying multipath channel.…”
