The traditional view of source coding with side information is in the block coding context in which all the source symbols are known in advance by the encoder. We instead consider a sequential setting in which source symbols are revealed to the encoder in real time and need to be reconstructed at the decoder within a certain fixed delay. We derive an upper bound on the reliability function with delay...
We study the information theoretic limits of communication over asynchronous discrete memoryless channels. The transmitter starts sending a block codeword of length N at a time v uniformly distributed within the interval [1, 2, ..., L]. We assume that the receiver knows L but not v. We give a scaling law of L with respect to N for which reliable communication can be achieved. Specifically, we propose...
