摘要：

We show that the Gaussian multiple-access channel (MAC) and broadcast channel (BC) are duals. The dual channels we consider have the same channel gains and the same noise power at all receivers. We find an expression for the capacity region of the BC in terms of the capacity region of the dual MAC, and vice versa. Duality applies to many different channel models and capacity definitions.
