Successive refinement via broadcast: Optimizing expected distortion of a Gaussian source over a Gaussian fading channel
收藏 引用
IEEE TRANSACTIONS ON INFORMATION THEORY 2008年 第7期54卷 2903-2918页
作者: Tian, Chao Steiner, Avi Shamai (Shitz), Shlomo Diggavi, Suhas N. Ecole Polytech Fed Lausanne Sch Comp & Commun Sci CH-1015 Lausanne Switzerland Technion Israel Inst Technol Dept Elect Engn IL-32000 Haifa Israel
We consider the problem of transmitting a Gaussian source on a slowly fading Gaussian channel, subject to the mean-squared error distortion measure. The channel state information is known only at the receiver but not ... 详细信息
