On Predictive coding for Erasure channels Using a Kalman Framework
收藏 引用
IEEE TRANSACTIONS ON SIGNAL PROCESSING 2009年 第11期57卷 4456-4466页
作者: Arildsen, Thomas Murthi, Manohar N. Andersen, Soren Vang Jensen, Soren Holdt Aalborg Univ Dept Elect Syst DK-9220 Aalborg Denmark Univ Miami Coral Gables FL 33146 USA
We present a new design method for robust low-delay coding of autoregressive (AR) sources for transmission across erasure channels. It is a fundamental rethinking of existing concepts. It considers the encoder a mecha... 详细信息

coding and Common Reconstruction
收藏 引用
IEEE TRANSACTIONS ON INFORMATION THEORY 2009年 第11期55卷 4995-5010页
作者: Steinberg, Yossef Technion Israel Inst Technol Dept Elect Engn IL-32000 Technion Haifa Israel
This work studies problems of source and joint source-channel coding under the requirement that the encoder can produce an exact copy of the compressed source constructed by the decoder. This requirement, termed here ... 详细信息

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

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

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

Adaptive Mode- and Diversity-Control for Video Transmission on MIMO Wireless channels
收藏 引用
IEEE TRANSACTIONS ON SIGNAL PROCESSING 2009年 第9期57卷 3624-3637页
作者: Hormis, Raju Linzer, Elliot Wang, Xiaodong Analog Devices Inc High Speed Signal Proc Grp Somerset NJ 08873 USA Ambarella Sunnyvale CA 94089 USA Columbia Univ Dept Elect Engn New York NY 10027 USA
Video transmitted over wireless channels incurs both encoder-induced distortion and distortion caused by transmission errors. To address these problems, we propose a framework to transmit video reliably over a Rayleig... 详细信息

16th IEEE International Conference on Image Processing
作者: Ardestani, Majid R. Aminlou, Alireza Shirazi, Ali Asghar Beheshti Iran Univ Sci & Technol Dept Elect Engn Tehran Iran Univ Tehran Dept Elect & Comp Engn Tehran Iran
An analysis-based approach for unequal loss-protected multiple description coding (packetization) of the scalable (prioritized / progressive) source code streams is proposed. For a given number of packets (description... 详细信息

On source Transmission Over MIMO channels With Limited Feedback
收藏 引用
IEEE TRANSACTIONS ON SIGNAL PROCESSING 2009年 第1期57卷 324-341页
作者: Kim, Tung T. Skoglund, Mikael Caire, Giuseppe Royal Inst Technol Sch Elect Engn Stockholm Sweden Royal Inst Technol Sch Elect Engn S-10044 Stockholm Sweden Royal Inst Technol ACCESS Linnaeus Ctr S-10044 Stockholm Sweden Univ So Calif Dept Elect Engn Los Angeles CA 90089 USA
The problem of source-channel coding over a multiple-antenna (MIMO) channel with quantized channel state information at the transmitter (CSIT) is considered. Upper bounds on the distortion exponents achieved with part... 详细信息

Universal source Controlled channel Decoding with Nonsystematic Quick-Look-In Turbo Codes
收藏 引用
IEEE TRANSACTIONS ON COMMUNICATIONS 2009年 第4期57卷 960-971页
作者: Shamir, Gil I. Xie, Kai ADC Telecomm Inc San Jose CA 95134 USA
Utilization of redundancy left in a channel coded sequence can improve channel decoding performance. Stronger improvement can usually be achieved with nonsystematic encoding. However, nonsystematic codes recently prop... 详细信息

MAP Decoding for Multi-Antenna Systems with Non-Uniform sources: Exact Pairwise Error Probability and Applications
收藏 引用
IEEE TRANSACTIONS ON COMMUNICATIONS 2009年 第1期57卷 242-254页
作者: Behnamfar, Firouz Alajaji, Fady Linder, Tamas Nortel Networks Ottawa ON K2H 8E9 Canada Queens Univ Dept Math & Stat Kingston ON K7L 3N6 Canada Queens Univ Dept Elect & Comp Engn Kingston ON K7L 3N6 Canada Hungarian Acad Sci Comp & Automat Res Inst H-1111 Budapest Hungary
We study the maximum a posteriori (MAP) decoding of memoryless non-uniform sources over multiple-antenna channels. Our model is general enough to include space-time coding, BLAST architectures, and single-transmit mul... 详细信息
