GLOBECOM '03. IEEE Global Telecommunications Conference (IEEE Cat. No.03CH37489)
作者: I. Bahceci Y. Altunbasak T.M. Duman School of Electrical and Computer Engineering Georgia Institute of Technology Atlanta GA USA Department of Electrical Engineering Arizona State University Tempe AZ USA
We propose a joint source-channel coding scheme for wireless communication systems with multiple transmit and receive antennas. The source coder is realized by a multiple description encoder that generates multiple bi... 详细信息

IEEE International Symposium on Information Theory
作者: E. Tuncel K. Rose Department of Electrical and Computer Engineering University of California Santa Barbara USA
A multiterminal source coding scenario known as robust descriptions coding, where the source is to be encoded in a way that enables good descriptions for several distortion measures simultaneously is considered. Our r... 详细信息

IEEE International Symposium on Information Theory
作者: U. Speidel Department of Computer Science Tamaki Campus University of Auckland Auckland New Zealand
Nicolescu and Titchener showed that every finite string could be used to generate a unique recursively constructed variable-length code set belonging to the family of the T-codes. This paper proposes a conventional en... 详细信息

Joint IST Symposium on Mobile Future, and the Symposium on Trends in Communications, SympoTIC
作者: M.A. Hosany K.M.S. Soyjaudah Faulty of Engineering Depamnent of Electrical and Electronic Engineering University of Mauritius Reduit Mauritius
A technique to combine the three processes of a digital communication system, namely source coding, channel coding and modulation, is presented. The proposed system employs Huffman code for source coding, run length l... 详细信息

Asilomar Conference on Signals, Systems & Computers
作者: Lingling Pu Zhenyu Wu A. Bilgin M.W. Marcellin B. Vasic Department of Electrical and Computer Engineering University of Arizona Tucson Tucson AZ USA
A framework for iterative joint source-channel decoding of JPEG2000 codestreams is presented in this paper. At the encoder, JPEG2000 is used to perform source coding with certain error resilience (ER) modes, and LDPC ... 详细信息

Data Compression Conference (DCC)
作者: A. Aaron S. Rane Rui Zhang B. Girod Information Systems Laboratory University of Stanford Stanford CA USA
Two separate applications of Wyner-Ziv coding of motion video coding are considered. The Wyner-Ziv theorem on source coding with side information available only at the decoder suggests that an asymmetric video codec, ... 详细信息
