摘要：

We consider robust communications through multi-input multi-output (MIMO) channels under channel uncertainty. We formulate the problem within a game-theoretic framework as a two-player zero-sum game with a mutual information payoff function in which the players are: the transmitter and a malicious nature. A Gaussian signaling with uniform power allocation is obtained as a robust solution (under a mild isotropy condition).
