Minimum Distortion Variance Concatenated Block Codes for Embedded Source Transmission

open access: yes, 2014
Some state-of-art multimedia source encoders produce embedded source bit streams that upon the reliable reception of only a fraction of the total bit stream, the decoder is able reconstruct the source up to a basic quality.

connection optimization of joint source and channel coding based on protograph LDPC codes [PDF]

open access: yes, 2016
香农的经典分离定理已证明,信源和信道编码分别达到最优时,整个系统的性能仍能保持最优。然而分离系统适用于码长无限长的点对点传输系统,并不适用于实际的传输系统中,联合信源信道编译码系统因为其良好的传输性能和低功耗的特点吸引了更多的关注。 目前存在很多联合信源信道编译码系统的设计方案,其中低密度奇偶校验码(LDPC码)由于其良好的逼近香农限的特点且较低的译码复杂度,被引入到信源和信道的编译码联合系统(JSCC)中,称之为D-LDPC的JSCC系统,为了更好的改进联合系统的性能和降低译码复杂度 ...

Cross-Layer QoS Control for Video Communications over Wireless Ad Hoc Networks

open access: yesEURASIP Journal on Wireless Communications and Networking, 2005
Assuming a wireless ad hoc network consisting of homogeneous video users with each of them also serving as a possible relay node for other users, we propose a cross-layer rate-control scheme based on an analytical study of how the effective video ...

Diffusion-Aided Joint Source Channel Coding for High Realism Wireless Image Transmission

open access: yesIEEE Transactions on Machine Learning in Communications and Networking
Deep learning-based joint source-channel coding (deep JSCC) has been demonstrated to be an effective approach for wireless image transmission. However, many current approaches utilize an autoencoder framework to optimize conventional metrics such as Mean

Asymptotic BER EXIT chart analysis for high rate codes based on the parallel concatenation of analog RCM and digital LDGM codes

open access: yesEURASIP Journal on Wireless Communications and Networking, 2019
This paper proposes an extrinsic information transfer (EXIT) chart analysis and an asymptotic bit error rate (BER) prediction method to speed up the design of high rate RCM-LDGM hybrid codes over AWGN and fast Rayleigh channels.
