Wiretap Channels With Causal State Information: Strong Secrecy [PDF]
IEEE Transactions on Information Theory, 2019 The coding problem for wiretap channels with causal channel state information available at the encoder and/or the decoder is studied under the strong secrecy criterion. This problem consists of two aspects: one is due to naive wiretap channel coding and the other is due to one-time pad cipher based on the secret key agreement between Alice and Bob ...

Optimizing Age of Information in Wireless Networks with Perfect Channel State Information
, 2018 Age of information (AoI), defined as the time elapsed since the last received update was generated, is a newly proposed metric to measure the timeliness of information updates in a network.

Robust cognitive beamforming with partial channel state information [PDF]
IEEE Transactions on Wireless Communications, 2009 This paper considers a spectrum sharing based cognitive radio (CR) communication system, which consists of a secondary user (SU) having multiple transmit antennas and a single receive antenna and a primary user (PU) having a single receive antenna. The channel state information (CSI) on the link of the SU is assumed to be perfectly known at the SU ...

Upper Bounds on the Capacities of Noncontrollable Finite-State Channels with/without Feedback
, 2012 Noncontrollable finite-state channels (FSCs) are FSCs in which the channel inputs have no influence on the channel states, i.e., the channel states evolve freely.

Exploiting Wireless Channel State Information for Throughput Maximization [PDF]
IEEE Transactions on Information Theory, 2004 We consider the problem of scheduling packets over channels with time-varying quality. This problem has received a lot of attention lately in the context of devising methods for providing quality of service in wireless communications. Earlier work dealing with this problem considered two cases.

Capacity of a POST Channel with and without Feedback
, 2013 We consider finite state channels where the state of the channel is its previous output. We refer to these as POST (Previous Output is the STate) channels. We first focus on POST($\alpha$) channels.
