Information Spectrum Approach to the Source Channel Separation Theorem
, 2013 A source-channel separation theorem for a general channel has recently been shown by Aggrawal et. al. This theorem states that if there exist a coding scheme that achieves a maximum distortion level d_{max} over a general channel W, then reliable ...

Deep Learning‐Driven Semantic Communication With Attention Modules
IET Communications, Volume 19, Issue 1, January/December 2025.In this study, an innovative architecture is proposed to enhance the performance of semantic communication networks by leveraging deep learning and Joint Source‐Channel Coding. A fundamental challenge in this field is the strong dependence of conventional networks on a fixed Signal‐to‐Noise Ratio (SNR) during training, which leads to performance ...

Energy‐Constrained Quality Optimization for Secure Image Transmission in Wireless Sensor Networks
Advances in Multimedia, Volume 2007, Issue 1, 2007., 2007 Resource allocation for multimedia selective encryption and energy efficient transmission has not been fully investigated in literature for wireless sensor networks (WSNs). In this article, we propose a new cross‐layer approach to optimize selectively encrypted image transmission quality in WSNs with strict energy constraint.

A Non‐Binary Dual Cascade Polar Codes Construction and Low‐Complexity SCL Decoding
Electronics Letters, Volume 61, Issue 1, January/December 2025.First, we design an error‐correction approach including two cascade non‐binary polar coding (NB‐CPolar) structures and a cyclic redundancy check (CRC) code. Second, we propose a low‐complexity decoding algorithm based on non‐binary successive cancellation list (NB‐LSCL) decoding.

Advances in Multimedia, Volume 2007, Issue 1, 2007., 2007 Cross‐layering is a design paradigm for overcoming the limitations deriving from the ISO/OSI layering principle, thus improving the performance of communications in specific scenarios, such as wireless multimedia communications. However, most available solutions are based on empirical considerations, and do not provide a theoretical background ...
