International Conference on Green Circuits and Systems (ICGCS)
作者: Muchen Li Xin Jin Satoshi Goto Graduate School of Information Production and System Waseda University Kitakyushu Japan Information Technology Research Organization Waseda University Kitakyushu Japan
In surveillance systems, ultra low bit rate video coding is necessary to reduce the storage and bandwidth consumption, especially for high definition video coding. This paper proposes a new architecture to further red... 详细信息

International ITG Conference on Source and Channel coding (SCC)
作者: Stephan Pfletschinger Monica Navarro Centre Tecnològic de Telecomunicacions de Catalunya Barcelona Spain
We consider a link adaptation scheme with adaptive coding and modulation and adaptive retransmissions on a block fading channel. Therefore, we characterize the performance of the employed channel code with puncturing ... 详细信息
