Precoding Methods for MISO Broadcast Channel with Delayed CSIT
CoRR, 2012 Recent information theoretic results suggest that precoding on the multi-user downlink MIMO channel with delayed channel state information at the transmitter (CSIT) could lead to data rates much beyond the ones obtained without any CSIT, even in extreme situations when the delayed channel feedback is made totally obsolete by a feedback delay exceeding ...

Broadcasting with delayed CSIT : finite SNR analysis and heterogeneous feedback
, 2016 Cette thèse explore, sous certains paramètres réalistes, l’une des techniques clés pour les réseaux sans fil de demain, i.e., la réduction des interférences permis par la voie de retour (feedback).

Delayed-Choice Experiments and the Metaphysics of Entanglement [PDF]
, 2012 Delayed-choice experiments in quantum mechanics are often taken to undermine a realistic interpretation of the quantum state. More specifically, Healey has recently argued that the phenomenon of delayed-choice entanglement swapping is incompatible with ...

DoF analysis of the MIMO broadcast channel with alternating/hybrid CSIT [PDF]
, 2015 We consider a K-user multiple-input singleoutput (MISO) broadcast channel (BC) where the channel state information (CSI) of user i(i = 1,2, .. ., K) may be instantaneously perfect (P), delayed (D), or not known (N) at the transmitter with probabilities ...

On the synergistic benefits of alternating CSIT for X channel within a four-symbol channel extension
, 2015 In this paper, we investigate the degrees of freedom (DoF) of the two-user single input single output (SISO) X channel with alternating channel state information at the transmitters (CSIT). Three cases are considered for the availability of CSIT; perfect,

MIMO interference alignment algorithms with hierarchical CSIT
, 2012 International audienceThis work1 deals with interference alignment (IA) in a K-users MIMO interference channel with only incomplete Channel State Information at the Transmitters (CSIT). Incompleteness of CSIT is defined by the perfect knowledge of only a

Delayed Channel State Information Incremental redundancy with backtrack retransmission
, 2014 In many practical wireless systems, the Signal-to-Interference-and-Noise Ratio (SINR) that is applicable to a certain transmission, referred to as Channel State Information (CSI), can only be learned after the transmission has taken place and is thereby ...

Secrecy degrees of freedom of the two-user MISO broadcast channel with mixed CSIT
, 2015 The secrecy degrees of freedom (SDOF) of the multiple-input single-output (MISO) broadcast channel with confidential messages (BCC) is studied. The network consists of a two-antenna transmitter and two single-antenna receivers, each demanding a ...
