IEEE TRANSACTIONS ON VEHICULAR TECHNOLOGY 2024年 第6期73卷 9077-9082页
作者: Yu, Kaiwen He, Qi Wu, Gang Univ Elect Sci & Technol China Natl Key Lab Wireless Commun Chengdu 611731 Peoples R China
Semantic communications can significantly improve transmission efficiency, especially in the low signal-to-noise (SNR) regime. However, two-way semantic communications still remain an unexplored topic, which is a crit... 详细信息

Multi-Way Relay Networks: Orthogonal Uplink, source-channel Separation and Code Design
收藏 引用
IEEE TRANSACTIONS ON COMMUNICATIONS 2013年 第2期61卷 753-768页
作者: Timo, Roy Lechner, Gottfried Ong, Lawrence Johnson, Sarah Univ S Australia Inst Telecommun Res Adelaide SA 5001 Australia Univ Newcastle Sch Elect Engn & Comp Sci Callaghan NSW 2308 Australia
We consider a multi-way relay network with an orthogonal uplink and correlated sources, and we characterise reliable communication (in the usual Shannon sense) with a single-letter expression. The characterisation is ... 详细信息

Cache-Aided K-User Broadcast channels With State Information at Receivers
收藏 引用
IEEE TRANSACTIONS ON INFORMATION THEORY 2024年 第4期70卷 2518-2537页
作者: Reisizadeh, Hadi Maddah-Ali, Mohammad Ali Mohajer, Soheil Univ Minnesota Twin Cities Dept Elect & Comp Engn Minneapolis MN 55455 USA
We study a K-user coded-caching broadcast problem in a joint source-channel coding framework. The transmitter observes a database of files that are being generated at a certain rate per channel use, and each user has ... 详细信息

Fast algorithm for rate-based optimal error protection of embedded codes
收藏 引用
IEEE TRANSACTIONS ON COMMUNICATIONS 2003年 第11期51卷 1788-1795页
作者: Stankovic, V Hamzaoui, R Saupe, D Texas A&M Univ Dept Elect Engn College Stn TX 77843 USA Univ Konstanz Dept Comp & Informat Sci D-78457 Constance Germany
Embedded image codes are very sensitive to channel noise because a single bit error can lead to an irreversible loss of synchronization between the encoder and the decoder. Sherwood and Zeger introduced a powerful sys... 详细信息
