The Gaussian Z-Interference Channel with Rate-Constrained Conferencing Decoders
H. T. Do, Tobias J. Oechtering, Mikael Skoglund · 2010
We derive achievable rate regions for a 2-user Gaussian Z-interference channel with conferencing decoders. We identify different cases where the rate-limitedness of the conference link from the interference-free receiver to the interfered receiver affects the conferencing strategy as well as the achievable rate region. Furthermore, an outer bound to the capacity region based on cut-set and genie-aided bounds is presented.
