An Achievable Rate Region for the Broadcast Channel with Feedback
, 2013 A single-letter achievable rate region is proposed for the two-receiver discrete memoryless broadcast channel with generalized feedback. The coding strategy involves block-Markov superposition coding, using Marton's coding scheme for the broadcast ...

Error-resilient performance of Dirac video codec over packet-erasure channel [PDF]
, 2007 Video transmission over the wireless or wired network requires error-resilient mechanism since compressed video bitstreams are sensitive to transmission errors because of the use of predictive coding and variable length coding.

Polar Codes for Broadcast Channels [PDF]
IEEE Transactions on Information Theory, 2013 Polar codes are introduced for discrete memoryless broadcast channels. For $m$-user deterministic broadcast channels, polarization is applied to map uniformly random message bits from $m$ independent messages to one codeword while satisfying broadcast constraints.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS
FEBS Letters, EarlyView.We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Iterative joint design of source codes and multiresolution channel codes [PDF]
, 1997 We propose an iterative design algorithm for jointly optimizing source and channel codes. The joint design combines channel-optimized vector quantization (COVQ) for the source code with rate-compatible punctured convolutional (RCPC) coding for the ...

Nash Codes for Noisy Channels [PDF]
Operations Research, 2014 This paper studies the stability of communication protocols that deal with transmission errors. We consider a coordination game between an informed sender and an uninformed receiver, who communicate over a noisy channel. The sender’s strategy, called a code, maps states of nature to signals.

Cell wall target fragment discovery using a low‐cost, minimal fragment library
FEBS Letters, EarlyView.LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

A survey on deep learning based joint source-channel coding
Dianxin kexue, 2020 Classical information theory shows that separate source-channel coding is asymptotically optimal over a point-to-point channel.As modern communication systems are becoming more sensitive to delays and bandwidth,it becomes difficult to adopt the ...

Dense coding capacity of a quantum channel
Physical Review Research, 2020 We consider the fundamental protocol of dense coding of classical information assuming that noise affects both the forward and backward communication lines between Alice and Bob.
