      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 ...

      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 ...

      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 ...

      Probabilistic QoS measures for optimal power control in fading channels 

      Lu, S.; Charalambous, Charalambos D. (2007)
      In this paper, we focus on computing the outage probability by allocating optimal transmitting powers when the system has a large number of transmitter-receiver pairs and each mobile has an enlarged margin of SIR. By ...

      Stochastic power control for time-varying flat fading wireless channels 

      Olama, M. M.; Shajaat, S. M.; Djouadi, S. M.; Charalambous, Charalambos D. (2005)
      The performance of stochastic optimal power control of time-varying wireless short-term flat fading channels, in which the evolution of the dynamical channel is described by a stochastic state space representation, is ...
