      On the channel capacity of wireless fading channels 

      Charalambous, Charalambos D.; Denic, S. (2002)
      The objectives of this paper are twofold. First, to point out the significance of certain results on stochastic processes in computing the channel capacity for flat fading wireless channels. Second, to design an optimal ...
