Secrecy for MISO broadcast channels via alternating CSIT
, 2015 broadcast channel with confidential messages (BCCM) is studied in which the nature of channel state information at the trans-mitter (CSIT) from each user can be of the form Ii, i = 1, 2 where I1, I2 ∈ {P,D,N}, and the forms P, D and N correspond to ...

Optimally bridging the gap from delayed to perfect CSIT in the K-user MISO BC
, 2016 International audienceThis work 1 derives the optimal Degrees-of-Freedom (DoF) of the K-User MISO Broadcast Channel (BC) with delayed Channel-State Information at the Transmitter (CSIT) and with additional current noisy CSIT where the channel estimation ...

Secrecy DoF of Blind MIMOME Wiretap Channel With Delayed CSIT
IEEE Transactions on Information Forensics and Security, 2018 We study the Gaussian multiple-input multiple-output multiple-eavesdropper wiretap channel where a transmitter wishes to communicate a confidential message to a legitimate receiver in the presence of eavesdroppers. Each node in the network is equipped with an arbitrary number of antennas.

Space-Time Encoded MISO Broadcast Channel With Outdated CSIT: An Error Rate and Diversity Performance Analysis [PDF]
, 2015 Studies of the MISO Broadcast Channel (BC) with delayed Channel State Information at the Transmitter (CSIT) have so far focused on the sum-rate and Degrees-of-Freedom (DoF) region analysis. In this paper, we investigate for the first time, the error rate

Achievable sum DoF of the K-user MIMO interference channel with delayed CSIT [PDF]
, 2016 This paper considers a K-user multiple-inputmultiple-output (MIMO) interference channel (IC) where 1) the channel state information obtained by the transmitters (CSIT) is completely outdated, and 2) the number of transmit antennas at each transmitter, i ...

On the degrees of freedom of two-hop MISO broadcast networks with mixed CSIT
, 2013 We consider a downlink two-hop MISO broadcast network with a 2-antenna source communicating to 2 single-antenna destinations, via 2 single-antenna relays.

Outdated CSIT can Achieve Full DoF in Heterogeneous Parallel Channels
, 2014 International audienceWe consider communication over heterogeneous parallel channels, where a transmitter is connected to two users via two parallel channels: (1) a MISO broadcast channel (BC), and (2) a noiseless rate-limited multicast channel.

On the achievable degrees of freedom of partially cooperative X networks with delayed CSIT [PDF]
, 2012 We investigate the achievable degrees of freedom (DoF) in K-user X networks (K × K X networks) with delayed channel state information at transmitters (CSIT), where partial cooperation (i.e. message sharing) is potentially allowed among transmitters.

A degrees of freedom-optimal scheme for SISO X channel with synergistic alternating CSIT
, 2014 In this paper, the degrees of freedom (DoF) of the two-user single input single output (SISO) X channel are investigated. Three cases are considered for the availability of channel state information at the transmitters (CSIT); perfect, delayed, and no ...
