Conference on Visual Communications and Image Processing 2008
作者: Farshchian, Masoud Pearlman, William A. Telephonics Farmingdale NY 11735 USA Rensselaer Polytech Inst ECSE Dept Troy NY 12180 USA
Recently, several methods that divide the original bitstream of an image/video progressive wavelet based source coders into multiple correlated substreams have been proposed. The principle behind transmitting independ... 详细信息

SCIENTIA IRANICA 2012年 第3期19卷 782-794页
作者: Ardestani, M. R. Shirazi, A. A. Beheshti Iran Univ Sci & Technol Image Proc Lab Sch Elect Engn Tehran Iran
Forward Error Correction (FEC) codes may be used to protect a video code stream against packet erasures or errors when passing through an error-prone network. To have maximum possible fidelity at the decoder side, an ... 详细信息

IEEE TRANSACTIONS ON SIGNAL PROCESSING 2012年 第12期60卷 6734-6739页
作者: Persson, Daniel Larsson, Erik G. Skoglund, Mikael Linkoping Univ Dept Elect Engn SE-58183 Linkoping Sweden Royal Inst Technol Sch Elect Engn SE-10044 Stockholm Sweden
We investigate fast joint source-channel decoding employed for communication over frequency-flat and frequency-selective block-fading multiple-input multiple-output channels. Our setting has applications for communica... 详细信息

IEEE TRANSACTIONS ON INFORMATION THEORY 2008年 第4期54卷 1393-1405页
作者: Holliday, Tim Goldsmith, Andrea J. Poor, H. Vincent Goldman Sachs New York NY 10004 USA Stanford Univ Dept Elect Engn Stanford CA 94305 USA Princeton Univ Sch Engn & Appl Sci Princeton NJ 08544 USA
A framework is developed for optimizing the tradeoff between diversity, multiplexing, and delay in multiple-input multiple-output (MIMO) systems to minimize end-to-end distortion. The goal is to find the optimal balan... 详细信息
