Design of ring convolutional trellis codes for MAP decoding of MPEG-4 images
收藏 引用
IEEE TRANSACTIONS ON COMMUNICATIONS 2004年 第7期52卷 1033-1037页
作者: Mahapakulchai, S Van Dyck, RE Kasetsart Univ Bangkok 10900 Thailand Natl Inst Stand & Technol Gaithersburg MD 20899 USA
We propose a trellis-coded modulation system using continuous-phase frequency-shift keying (CPFSK) and ring convolutional codes for transmitting the bits generated by an embedded zerotree wavelet encoder. Improved per... 详细信息

Benefits of Cache Assignment on Degraded Broadcast channels
收藏 引用
IEEE TRANSACTIONS ON INFORMATION THEORY 2019年 第11期65卷 6999-7019页
作者: Bidokhti, Shirin Saeedi Wigger, Michele Yener, Aylin Univ Penn Dept Elect & Syst Engn Philadelphia PA 19104 USA IP Paris Telecom Paris LTCI F-75013 Paris France Penn State Univ Dept Elect Engn Sch Elect Engn & Comp Sci State Coll PA 16802 USA
Degraded K-user broadcast channels (BCs) are studied when the receivers are facilitated with cache memories. Lower and upper bounds are derived on the capacity-memory tradeoff, i.e., on the largest rate of reliable co... 详细信息

Optimal resource allocation for Medium Grain Scalable video transmission over MIMO channels
收藏 引用
JOURNAL OF VISUAL COMMUNICATION AND IMAGE REPRESENTATION 2013年 第3期24卷 373-387页
作者: Hamidouche, Wassim Olivier, Christian Pousset, Yannis Perrine, Clency Univ Poitiers CNRS Dept Signal Image & Commun XLIM LabUMR 7252 Poitiers France
In this paper we investigate an optimal solution for adaptive H.264/SVC video transmission over Multiple-Input Multiple-Output (MIMO) channels. We first write the end-to-end distortion of the H.264/SVC video transmiss... 详细信息

Iterative Encoder-Controller Design for Feedback Control Over Noisy channels
收藏 引用
IEEE TRANSACTIONS ON AUTOMATIC CONTROL 2011年 第2期56卷 265-278页
作者: Bao, Lei Skoglund, Mikael Johansson, Karl Henrik Royal Inst Technol KTH Sch Elect Engn ACCESS Linnaeus Ctr SE-10044 Stockholm Sweden
We study a closed-loop control system with state feedback transmitted over a noisy discrete memoryless channel. With the objective to minimize the expected linear quadratic cost over a finite horizon, we propose a joi... 详细信息
