An Extremal Inequality Motivated by Multiterminal Information-Theoretic Problems Conference Paper uri icon


  • We prove a new extremal inequality, motivated by the vector Gaussian broadcast channel and the distributed source coding with a single quadratic distortion constraint problems. As a corollary, this inequality yields a generalization of the classical entropy-power inequality (EPI). As another corollary, this inequality sheds insight into maximizing the differential entropy of the sum of two dependent random variables. 2007 IEEE.
