Abstract
The restriction to Gaussian inputs in the limiting expression for
the capacity regions of memoryless Gaussian interference and
multiple-access channels is shown to fall short of achieving capacity
even if the inputs are allowed to be dependent and nonstationary. In
addition, the equality between the limiting and the single-letter
characterizations of memoryless multiple-access channel capacity is
established directly, without recourse to independent coding theorems
