Abstract
We show that the Lagrange dual of the problem of channel capacity with input cost for discrete memoryless channel is a simple and well-structured geometric program. The geometric program dual gives a new class of upper bounds of channel capacity that can be made arbitrarily tight and includes some known bounds as special cases, and a free energy interpretation to channel capacity.
