摘要

数据结构是影响信息隐藏通信实时性能的关键技术.为此

系统设计需要对信源统计、信道状态与传输码率之间进行折衷考虑.按照信息隐藏通信的要求

把信源的统计特性以边信息在解码端进行处理

本文提出了一种非对称数据结构实现信息隐藏通信的方法.结合图像系数的方差分布和不同WNR环境下的信道状态

该方法能够降低了系统编解码实现的复杂性.分别应用SCS和QIM(DC-DM)及SS技术

结果表明

该方法实现的通信系统都具有较好的折衷性能.

Abstract

Data structure is one of the key technologies for real-time information-hiding communication system.Therefore

the system design should be a related problem between source statistics and channel state as well as transmission rates.To satisfy some requirements with side-information at decoder

the paper presents a new method to approach information-hiding communication performances with asymmetric data structure.By means of variances distribution of image coefficients and channel states under various WNR

the proposed method can reduce system complex.Comparing the theoretical results by experimentation considered SCS and QIM(DC-DM)as well as SS techniques

the communication system possess the good trade-off performances.
