Proof of the Outage Probability Conjecture for MISO Channels [PDF]
IEEE Transactions on Information Theory, 2012 In Telatar 1999, it is conjectured that the covariance matrices minimizing the outage probability for MIMO channels with Gaussian fading are diagonal with either zeros or constant values on the diagonal. In the MISO setting, this is equivalent to conjecture that the Gaussian quadratic forms having largest tale probability correspond to such diagonal ...

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 ...
