摘要: We prove a new outer bound to the capacity region of certain class interference channels, and quantify gap between it Han-Kobayashi inner bound. The allows recovery El Gamal-Costa characterization deterministic also recent by Etkin, Tse Wang scalar Gaussian channels within '1 bit'. Moreover, straightforward generalization bit' result vector channels.
