Joint source-channel coding with feedback [PDF]
IEEE Transactions on Information Theory, 2017 This paper quantifies the fundamental limits of variable-length transmission of a general (possibly analog) source over a memoryless channel with noiseless feedback, under a distortion constraint.

Joint Source-Channel Secrecy Using Hybrid Coding [PDF]
2015 IEEE International Symposium on Information Theory (ISIT), 2015 The secrecy performance of a source-channel model is studied in the context of lossy source compression over a noisy broadcast channel. The source is causally revealed to the eavesdropper during decoding.

Distributed Joint Source-Channel Coding Using Quasi-Uniform Systematic Polar Codes [PDF]
Entropy, 2018 This paper proposes a distributed joint source-channel coding (DJSCC) scheme using polar-like codes. In the proposed scheme, each distributed source encodes source message with a quasi-uniform systematic polar code (QSPC) or a punctured QSPC, and only ...

Channel-Blind Joint Source–Channel Coding for Wireless Image Transmission [PDF]
SensorsJoint source–channel coding (JSCC) based on deep learning has shown significant advancements in image transmission tasks. However, previous channel-adaptive JSCC methods often rely on the signal-to-noise ratio (SNR) of the current channel for encoding ...

LDGM Codes for Channel Coding and Joint Source-Channel Coding of Correlated Sources
EURASIP Journal on Advances in Signal Processing, 2005 We propose a coding scheme based on the use of systematic linear codes with low-density generator matrix (LDGM codes) for channel coding and joint source-channel coding of multiterminal correlated binary sources. In both cases, the structures of the LDGM

Distributed Joint Source-Channel Coding in Wireless Sensor Networks [PDF]
Sensors, 2009 Considering the fact that sensors are energy-limited and the wireless channel conditions in wireless sensor networks, there is an urgent need for a low-complexity coding method with high compression ratio and noise-resisted features.

Zero-Delay Joint Source Channel Coding for a Bivariate Gaussian Source over the Broadcast Channel with One-Bit ADC Front Ends [PDF]
Entropy, 2021 In this work, we consider the zero-delay transmission of bivariate Gaussian sources over a Gaussian broadcast channel with one-bit analog-to-digital converter (ADC) front ends. An outer bound on the conditional distortion region is derived.

Natural chunk-and-pass language processing: Just another joint source-channel coding model? [PDF]
Communicative & Integrative Biology, 2018 A recent theoretical treatment by Christiansen and Chater attempts to address fundamental challenges significant to language processing and evolution with one major operational constraint called the “Now-or-Never” bottleneck. The authors' “Chunk-and-Pass”
