Information Capacity of Additive Gaussian Channels with Jamming

摘要

Information capacity is determined for the matched Gaussian channel when jamming is added to the ambient noise. The problem is modeled as a zero-sum two-person game, with mutual information as the payoff function. The saddle value, a saddle point, and an optimum jammer strategy are given for both the finite-dimensional and the infinite-dimensional channel. (rh)
