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 ...
