We provide a single letter characterization of the capacity region for independent, identically distributed, finite-state channels, with partial (quantized) state information, when the channel state information is available at the receiver. The partial state information is asymmetric at the encoders. The problem is practically relevant, and provides a tractable optimization problem. We also consider...
We study cost constrained side-information channels, where the cost function depends on a state which is known only to the encoder. In the additive noise case, we bound the capacity loss due to not knowing the cost state at the decoder and show that it is small under various assumptions, and goes to zero in the limit of weak noise. This model plays an important role in the (non-degraded) broadcast...
