SNR-EQ-JSCC: Joint Source-Channel Coding With SNR-Based Embedding and Query [PDF]

IEEE Wireless Communications Letters
Coping with the impact of dynamic channels is a critical issue in joint source-channel coding (JSCC)-based semantic communication systems. In this paper, we propose a lightweight channel-adaptive semantic coding architecture called SNR-EQ-JSCC. It is built upon the generic Transformer model and achieves channel adaptation (CA) by Embedding the signal ...

Secure Deep-JSCC Against Multiple Eavesdroppers [PDF]

GLOBECOM 2023 - 2023 IEEE Global Communications Conference, 2023
In this paper, a generalization of deep learning-aided joint source channel coding (Deep-JSCC) approach to secure communications is studied. We propose an end-to-end (E2E) learning-based approach for secure communication against multiple eavesdroppers over complex-valued fading channels.

Disentangled Information Bottleneck guided Privacy-Protective JSCC for Image Transmission [PDF]

arXiv.org, 2023
Joint source and channel coding (JSCC) has attracted increasing attention due to its robustness and high efficiency. However, JSCC is vulnerable to privacy leakage due to the high relevance between the source image and channel input. In this paper, we propose a disentangled information bottleneck guided privacy-protective JSCC (DIB-PPJSCC) for image ...

Radiomic score for lung nodules as a prognostic biomarker in locally advanced rectal cancer patients: A bi-institutional study. [PDF]

Cancer Med
Abstract Background Undetermined lung nodules are common in locally advanced rectal cancer (LARC) and lack precise risk stratification. This study aimed to develop a radiomic‐based score (Rad‐score) to distinguish metastasis and predict overall survival (OS) in patients with LARC and lung nodules.

Clinical features of low serum alkaline phosphatase levels in children: A retrospective study. [PDF]

Pediatr Int
Abstract Background Serum alkaline phosphatase (ALP), a biomarker of bone and liver metabolism, is often elevated in children; however, the lower reference limit is rarely considered. Hypophosphatasia (HPP) is characterized by low ALP levels and impaired mineralization of bone and teeth.

Rate–Distortion–Perception Optimized Neural Speech Transmission System for High-Fidelity Semantic Communications [PDF]

Sensors
We consider the problem of learned speech transmission. Existing methods have exploited joint source–channel coding (JSCC) to encode speech directly to transmitted symbols to improve the robustness over noisy channels.

D²-JSCC: Digital Deep Joint Source-channel Coding for Semantic Communications

2024 IEEE 35th International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC)
Semantic communications (SemCom) have emerged as a new paradigm for supporting sixth-generation applications, where semantic features of data are transmitted using artificial intelligence algorithms to attain high communication efficiencies. Most existing SemCom techniques utilize deep neural networks (DNNs) to implement analog source-channel mappings,
