Outage Probability Under Channel Distribution Uncertainty [PDF]
IEEE Transactions on Information Theory, 2011 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 belong to a class of distributions where each member is within a certain distance (uncertainty) from a nominal distribution ...

Optimum Power Randomization for the Minimization of Outage Probability [PDF]
IEEE Transactions on Wireless Communications, 2013 The optimum power randomization problem is studied to minimize outage probability in flat block-fading Gaussian channels under an average transmit power constraint and in the presence of channel distribution information at the transmitter. When the probability density function of the channel power gain is continuously differentiable with a finite ...
