Abstract :
The general Han and Kobayashi (HK) region is not computable for the Gaussian Interference Channel. A modified (i.e., non-naive) FDM/TDM method was proposed that remains the largest computable achievable region to date. In this paper, we show that the naive FDM/TDM turns out to be sum rate optimal for a certain range of channel parameters within this class of computable achievable region.
