      Capacity of the class of MIMO channels with incomplete CDI - Properties of mutual information for a class of channels 

      Charalambous, Charalambos D.; Denic, S. Z.; Constantinou, C. (2009)
      This paper is concerned with multiple-input multiple-output (MIMO) wireless channel capacity, when the probability distribution of the channel matrix p(H) is not completely known to the transmitter and the receiver. The ...

      Feedback does not increase the capacity of compound channels with additive noise 

      Loyka, S.; Charalambous, Charalambos D. (Institute of Electrical and Electronics Engineers Inc., 2016)
      A discrete compound channel with memory is considered, where no stationarity, ergodicity or information stability is required, and where the uncertainty set can be arbitrary. When the discrete noise is additive but otherwise ...

      A General Formula for Compound Channel Capacity 

      Loyka, S.; Charalambous, Charalambos D. (2016)
      A general formula, for the capacity of arbitrary compound channels with the receiver channel state information, is obtained using the information density approach. No assumptions of ergodicity, stationarity, or information ...

      A general formula for compound channel capacity 

      Loyka, S.; Charalambous, Charalambos D. (Institute of Electrical and Electronics Engineers Inc., 2015)
      A general formula for the capacity of arbitrary compound channels, which are not necessarily ergodic, stationary or information-stable, is obtained using the information density approach. A direct (constructive) proof is ...

      Information theoretic bounds for compound MIMO Gaussian channels 

      Denic, S. Z.; Charalambous, Charalambos D.; Djouadi, S. M. (2009)
      In this paper, achievable rates for compound Gaussian multiple-input-multiple-output (MIMO) channels are derived. Two types of channels, modeled in the frequency domain, are considered when: 1) the channel frequency response ...

      Minimizing outage probability for a class of MIMO channels 

      Charalambous, Charalambos D.; Ioannou, I. (2009)
      In this paper we investigate the outage probability of Multiple-Input Multiple-Output (MIMO) channels, when the probability distribution of the channel gains is not completely known to the transmitter and receiver. The ...

      Novel Matrix Singular Value Inequalities and Their Applications to Uncertain MIMO Channels 

      Loyka, S.; Charalambous, Charalambos D. (2015)
      Novel matrix singular value inequalities are established for a sum/product of three matrices. Their application to the uncertain (compound) multiple-input multiple-output (MIMO) channel subject to normed additive uncertainty ...

      On the compound capacity of a class of MIMO channels subject to normed uncertainty 

      Loyka, S.; Charalambous, Charalambos D. (2012)
      The compound capacity of uncertain multiple-input multiple-output channels is considered, when the channel is modeled by a class described by a (known) nominal channel and a constrained-norm (unknown) uncertainty. Within ...
