Generalized Common Informations: Measuring Commonness by the Conditional Maximal Correlation
Lei Yu, Houqiang Li, Chang Wen Chen
In literature, different common informations were defined by Gács and Körner, by Wyner, and by Kumar, Li, and Gamal, respectively. In this paper, we define two generalized versions…
Comments on "Approximate Characterizations for the Gaussian Source Broadcast Distortion Region"
Lei Yu, Houqiang Li, Weiping Li
Recently, Tian et al. [1] considered joint source-channel coding of transmitting a Gaussian source over -user Gaussian broadcast channel, and derived an outer bound on the admis…
Joint Source-Channel Secrecy Using Uncoded Schemes: Towards Secure Source Broadcast
Lei Yu, Houqiang Li, Weiping Li
This paper investigates a joint source-channel secrecy problem for the Shannon cipher broadcast system. We suppose list secrecy is applied, i.e., a wiretapper is allowed to produce…
Distortion Bounds for Transmitting Correlated Sources with Common Part over MAC
Lei Yu, Houqiang Li, Chang Wen Chen
This paper investigates the joint source-channel coding problem of sending two correlated memoryless sources with common part over a memoryless multiple access channel (MAC). An in…
Distortion Bounds for Source Broadcast Problems
Lei Yu, Houqiang Li, Weiping Li
This paper investigates the joint source-channel coding problem of sending a memoryless source over a memoryless broadcast channel. An inner bound and several outer bounds on the a…
Source-Channel Secrecy for Shannon Cipher System
Lei Yu, Houqiang Li, Weiping Li
Recently, a secrecy measure based on list-reconstruction has been proposed [2], in which a wiretapper is allowed to produce a list of reconstruction sequences and the…
