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

Minimum Distortion Variance Concatenated Block Codes for Embedded Source Transmission
, 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.

Veterinary Clinical Pathology, Volume 53, Issue 2, Page 218-228, June 2024.Abstract Background Biochemical measurements are commonly evaluated using population‐based reference intervals; however, there is a growing trend toward reassessing results with within‐subject variation (CVI). Objectives We aimed to estimate the CVI of 16 biochemical analytes using a large database of dogs and cats, which refers to the results of ...
