symmetric channel meaning in Chinese
对称信道, 对称通道
Examples
- Binary symmetric channel
二进制对称道 - In chapter 5 , we define quantum binary symmetric channels via the invariance of fidelity under unitary transformation of input density operators
第五章通过量子保真度( fidelity )在输入信号的幺正变换下的不变性定义了量子二进制对称信道。 - In the new model , the legitimate partners can control the error bit rate of the eavesdropper ' s channel by adjusting their virtual binary symmetric channels . when our new model is implemented , the problem of receiving synchronization of the partners will not occur
在该模型中，通信双方使用虚拟的二元对称信道来控制窃听方接收信道的误比特率，而且使用该模型也不存在信息接收同步的问题。 - This paper can put into four parts ? this first part is the description and theoretical analyses of source coding , which focus on the research of optimizing equal quantization ? the second part presents the theoretical description of joint channel - source coding , which focus on the research of combined channel - source coding o the third part is about the application of combined channel - source coding to two different channel models , binary symmetric channel and cdma channel o in this part , two different coding designs are given according to different characters of these two channels ? and the last part is the description of simulation of combined channel - source coding ? most of my work are about two parts , one is to find the most appropriate quantization steps and centroid points of separate channel - source coding , another is to simulate the combined channel - source coding ? comparing the simulation results of separate channel - source coding and combined channel - source coding , the characters of joint channel - source coding are given
本论文可以分成四部分：第一部分给出了信源编码的基本概念和理论分析，重点放在最优均匀量化编码的研究方面；第二部分给出了信道?信源联合编码的原理叙述，重点放在复合式信道?信源编码的分析研究上；第三部分将信道-信源联合编码原理应用在两种噪声信道上：离散无记忆信道和cdma信道，并根据两种信道的不同特点详细描述了两种相应的编码设计方案；第四部分给出了复合式信道-信源编码的仿真结果以及对结果的相应分析。
