The Arbitrarily Varying Broadcast Channel with Degraded Message Sets with Causal Side Information at the Encoder
In this work, we study the arbitrarily varying broadcast channel (AVBC), when state information is available at the transmitter in a causal manner. We establish inner and outer bounds on both the random code capacity region and the deterministic code capacity region with degraded message sets. The capacity region is then determined for a class of channels satisfying a condition on the mutual in...
متن کاملA Study on Arbitrarily Varying Channels with Causal Side Information at the Encoder
In this work, we study two models of arbitrarily varying channels, when causal side information is available at the encoder in a causal manner. First, we study the arbitrarily varying channel (AVC) with input and state constraints, when the encoder has state information in a causal manner. Lower and upper bounds on the random code capacity are developed. A lower bound on the deterministic code ...
متن کاملThe Multiple Access Channel with Causal and Strictly Causal Side Information at the Encoders
We study the state-dependent multiple access channel (MAC) with causal side information at the encoders. We consider two general models. In the first model, the state sequence is available at the two encoders in a strictly causal manner. We derive an achievable region, which is tight for the special case of a Gaussian MAC where the state sequence comprises the channel noise. Although the two se...
متن کاملCapacity of Block-Memoryless Channels with Causal Channel Side Information
The capacity of a time-varying block-memoryless channel in which the transmitter and the receiver have access to (possibly different) noisy causal channel side information (CSI) is obtained. It is shown that the capacity formula obtained in this correspondence reduces to the capacity formula reported in [1] for the special case where the transmitter CSI is a deterministic function of the receiv...
متن کاملSource Coding with Causal Side Information at the Decoder
2 ⌋ }. The i-th reconstruction is of the form X̂i(T, Y ), i.e., it is allowed to depend on the side information, but only causally. The motivation for studying this problem comes from source coding systems that are constrained to operate with no, or with limited, delay. Sequential source codes with a limited-delay encoder and a sequential, zero-delay, decoder with access to side information comp...
