      Capacity for MIMO systems at low SNR 

      Ioannou, I.; Charalambous, Charalambos D.; Denic, S. (2010)
      The paper introduces an asymptotic series expansion for the mutual information of Multiple-Input Multiple-Output (MIMO) channels. For low signal to noise ratio (SNR) the first term of expansion approaches mutual information ...

      Ergodic capacity under channel distribution uncertainty 

      Loyka, S.; Charalambous, Charalambos D.; Ioannou, I. (Institute of Electrical and Electronics Engineers Inc., 2014)
      The impact of channel distribution uncertainty on the performance of fading channels is studied. The compound capacity of a class of ergodic fading channels subject to channel distribution uncertainty is obtained, for ...

      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 ...

      Mutual information expansion for MIMO systems and capacity formulae at low SNR 

      Ioannou, I.; Charalambous, Charalambos D.; Denic, S. (2011)
      The paper introduces a new asymptotic series expansion for the mutual information of multiple-input multiple-output (MIMO) channels. The expansion approaches mutual information from below, and for low signal to noise ratio ...

      Outage capacity and probability for a class of MIMO channels 

      Ioannou, I.; Charalambous, Charalambos D. (2010)
      This paper is concerned with outage capacity and probability of Multiple-Input Multiple-Output (MIMO) systems for a class of channel distributions. The results illustrate how outage probability and capacity degrade as a ...

      Outage probability under channel distribution uncertainty 

      Ioannou, I.; Charalambous, Charalambos D.; Loyka, S. (2012)
      Outage probability and capacity of a class of block-fading MIMO channels are considered under partial channel distribution information. Specifically, the channel or its distribution is not known but the latter is known to ...

      Outage probability under channel distribution uncertainty 

      Ioannou, I.; Charalambous, Charalambos D.; Loyka, S. (2011)
      Outage probability of a class of block-fading (MIMO) channels is considered under channel distribution uncertainty, when the channel or its distribution are not known but the latter is known to belong to a class of ...
