Multiple-Description coding by Dithered Delta-Sigma Quantization
收藏 引用
IEEE TRANSACTIONS ON INFORMATION THEORY 2009年 第10期55卷 4661-4675页
作者: Ostergaard, Jan Zamir, Ram Aalborg Univ Dept Elect Syst Aalborg Denmark Tel Aviv Univ Dept Elect Engn Syst IL-69978 Tel Aviv Israel
We address the connection between the multiple-description (MD) problem and Delta-Sigma quantization. The inherent redundancy due to oversampling in Delta-Sigma quantization, and the simple linear-additive noise model... 详细信息

Packet-by-packet adaptive scheme for video coding and transmission over wireless IP networks using rate-compatible punctured turbo (RCPT) codes
收藏 引用
WIRELESS PERSONAL COMMUNICATIONS 2007年 第4期43卷 1675-1687页
作者: Pei, Yong Arnbetkar, Viraj S. Wright State Univ Dept Comp Sci & Engn Dayton OH 45435 USA
In this paper, we consider real-time video coding and transmission over packet-switched wireless IP networks, such as WLAN, using RCPT codes and joint source-channel coding (JSCC) with concentration on a packet-by-pac... 详细信息

A Minimum Mean-Squared Error Relay for the Two-Way Relay channel with Network coding
收藏 引用
IEEE COMMUNICATIONS LETTERS 2009年 第3期13卷 196-198页
作者: Park, Moonseo Kim, Seong-Lyun Ajou Univ Div Elect & Comp Engn Commun Syst Lab Suwon 443749 South Korea Yonsei Univ Sch Elect & Elect Engn Radio Resource Management & Optimizat Lab Seoul 120749 South Korea
In this letter, we consider the two-way relay channel (TWRC) employing network coding. In TWRC, a conventional relay first decodes symbols from each user and combines (network coding) them using, for example, the XOR ... 详细信息

Rate and power allocation for layered transmission with superposition coding
收藏 引用
IEEE SIGNAL PROCESSING LETTERS 2007年 第11期14卷 773-776页
作者: Etemadi, Farzad Jafarkhani, Hamid Univ Calif Irvine Ctr Pervasive Communicat & Comp Dept Elect Engn & Comp Sci Irvine CA 92697 USA
We consider layered transmission of a Gaussian source over a quasi-static fading channel. A broadcast strategy is used in which multiple layers of source data are superimposed, and each layer is allocated a different ... 详细信息

source and channel coding for Homogeneous Sensor Networks with Partial Cooperation
收藏 引用
IEEE TRANSACTIONS ON WIRELESS COMMUNICATIONS 2009年 第3期8卷 1113-1117页
作者: Simeone, O. New Jersey Inst Technol CWCSPR Newark NJ 07102 USA
A sensor networks in which two nodes communicate a remote measurement to an access point is investigated (CEO problem). The focus is on assessing the performance advantages of cooperative encoding strategies as enable... 详细信息

IEEE International Symposium on Information Theory (ISIT)
作者: Koeken, Erman Tuncel, Ertem Univ Calif Riverside Riverside CA 92521 USA
The problem of lossy transmission of a Gaussian source over an AWGN bandwidth-mismatched broadcast channel with three receivers is addressed. The tradeoff between the distortion levels at the good and the bad receiver... 详细信息

International Conference on Image Processing (ICIP 2001)
作者: Pei, Y Modestino, JW Rensselaer Polytech Inst Ctr Image Proc Res Elect Comp & Syst Engn Dept Troy NY 12180 USA
In this paper we describe a multi-layered video transport scheme for wireless channels capable of adapting to channel conditions in order to maximize end-to-end quality of service (QoS). This scheme combines a scalabl... 详细信息

15th IEEE International Symposium on Personal, Indoor, Mobile, Radio Communications (PIMRC 2004)
作者: Tavares, J Navarro, A Univ Aveiro Inst Telecommun P-3810 Aveiro Portugal
In this paper, we present an adaptive scheme for forward error protection of any video coding standard. The channel coding rate changes according to the channel bit error rate (BER). The results are impressive. For in... 详细信息

Remote source coding Under Gaussian Noise: Dueling Roles of Power and Entropy Power
收藏 引用
IEEE TRANSACTIONS ON INFORMATION THEORY 2019年 第7期65卷 4486-4498页
作者: Eswaran, Krishnan Gastpar, Michael Univ Calif Berkeley Dept Elect Engn & Comp Sci Berkeley CA 94720 USA Google Inc Hlth Res Team Mountain View CA 94043 USA Ecole Polytech Fed Lausanne Sch Comp & Commun Sci CH-1015 Lausanne Switzerland
The distributed remote source coding (the so-called CEO) problem is studied in the case where the underlying source, not necessarily Gaussian, has finite differential entropy and the observation noise is Gaussian. The... 详细信息

Successive Segmentation-Based coding for Broadcasting Over Erasure channels
收藏 引用
IEEE TRANSACTIONS ON INFORMATION THEORY 2016年 第6期62卷 3026-3038页
作者: Tan, Louis Li, Yao Khisti, Ashish Soljanin, Emina Univ Toronto Dept Elect & Comp Engn Toronto ON M5S 3G4 Canada Akamai Technol Inc Santa Clara CA 95054 USA Rutgers State Univ Dept Elect & Comp Engn Piscataway NJ 08854 USA
Motivated by error correction coding in multimedia applications, we study the problem of broadcasting a single common source to multiple receivers over heterogeneous erasure channels. Each receiver is required to part... 详细信息
