The Capacity Region of a Class of Discrete Degraded Interference Channels
<|reference_start|>The Capacity Region of a Class of Discrete Degraded Interference Channels: We provide a single-letter characterization for the capacity region of a class of discrete degraded interference channels (DDICs). The class of DDICs considered includes the discrete additive degraded interference channel (DADIC) studied by Benzel. We show that for the class of DDICs studied, encoder cooperation does not increase the capacity region, and therefore, the capacity region of the class of DDICs is the same as the capacity region of the corresponding degraded broadcast channel.<|reference_end|>
