source-channel-cooperation tradeoffs for adaptive coded communications
收藏 引用
IEEE TRANSACTIONS ON WIRELESS COMMUNICATIONS 2008年 第9期7卷 3347-3358页
作者: Kwasinski, Andres Liu, K. J. Ray Rochester Inst Technol Rochester NY 14623 USA Univ Maryland College Pk MD 20742 USA
Transmit power limitations and quality-impairing channels present key challenges to wireless communications. A possible solution to these problems is the application of user-cooperation techniques so as to improve lin... 详细信息

19th IEEE International Symposium on Personal, Indoor and Mobile Radio Communications
作者: Park, Moonseo Kim, Seong-Lyun Yonsei Univ Sch Elect & Elect Engn Radio Resource Management & Optimizat Lab Seoul 120749 South Korea
The XOR network code is widely used in the conventional network coding. However, when the channel is noisy, the XOR code is suboptimal in terms of minimizing distortion in the source signal. We propose to use a new ne... 详细信息

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

IEEE TRANSACTIONS ON INFORMATION THEORY 2008年 第5期54卷 1850-1859页
作者: Kim, Young-Han Sutivong, Arak Cover, Thomas M. Stanford Univ Dept Elect Engn Stanford CA 94305 USA Stanford Univ Dept Stat Stanford CA 94305 USA
We consider the problem of transmitting data at rate R over a state-dependent channel p (y vertical bar x, s) with state information available at the sender and at the same time conveying the information about the cha... 详细信息

IEEE TRANSACTIONS ON INFORMATION THEORY 2008年 第1期54卷 332-343页
作者: Maor, Alina Merhav, Neri Technion Israel Inst Technol Dept Elect Engn IL-32000 Haifa Israel
Consider a process, {X-i, Y-i, Z(i)}(i=1)(infinity) producing independent copies of a triplet of jointly distributed random variables (RVs). The {X-i} I part of the process-the source-is observed at the encoder, and i... 详细信息

joint source-channel codes for MIMO block-fading channels
收藏 引用
IEEE TRANSACTIONS ON INFORMATION THEORY 2008年 第1期54卷 116-134页
作者: Gunduz, Deniz Erkip, Elza Polytech Univ Dept Elect & Comp Engn Brooklyn NY 11201 USA Stanford Univ Dept Elect Engn Stanford CA 94305 USA
We consider transmission of a continuous amplitude source over an L-block Rayleigh-fading M-t x M-r, multiple-input multiple-output (MIMO) channel when the channel state information is only available at the receiver. ... 详细信息

Parity-check matrix calculation for paraunitary oversampled DFT filter banks
收藏 引用
IEEE TRANSACTIONS ON SIGNAL PROCESSING 2008年 第10期56卷 5277-5283页
作者: Karp, Tanja Kieffer, Michel Duhamel, Pierre Texas Tech Univ Dept Elect & Comp Engn Lubbock TX 79409 USA Univ Paris 11 CNRS SUPELEC Lab Signaux & Syst F-91192 Gif Sur Yvette France
joint source-channel coding schemes based on oversampled filter banks were recently proposed. Oversampled filter banks are considered as error-correcting codes, extending the notion of code subspace, parity-check matr... 详细信息

A unified framework for layered transmission over fading and packet erasure channels
收藏 引用
IEEE TRANSACTIONS ON COMMUNICATIONS 2008年 第4期56卷 565-573页
作者: Etemadi, Farzad Jafarkhani, Hamid Univ Calif Irvine Dept EECS Irvine CA 92717 USA
We consider layered transmission of a successively refinable source over a quasi-static fading channel. We establish a duality relationship between this problem and that of packet transmission over erasure channels an... 详细信息

Error-resilient video encoding and transmission in multirate wireless LANs
收藏 引用
IEEE TRANSACTIONS ON MULTIMEDIA 2008年 第5期10卷 691-700页
作者: Argyriou, Antonios Philips Res Labs NL-5656 AE Eindhoven Netherlands
In this paper, we present a cross-layer approach for video transmission in wireless LANs that employs joint source and application-layer channel coding, together with rate adaptation at the wireless physical layer (PH... 详细信息

Uncoded Transmission Is Exactly Optimal for a Simple Gaussian "Sensor" Network
收藏 引用
IEEE TRANSACTIONS ON INFORMATION THEORY 2008年 第11期54卷 5247-5251页
作者: Gastpar, Michael Univ Calif Berkeley Dept Elect Engn & Comp Sci Berkeley CA 94720 USA
A single memoryless Gaussian source is observed by many terminals, subject to independent Gaussian observation noises. The terminals are linked to a fusion center via a standard Gaussian multiple-access channel. The f... 详细信息
