LDGM codes for channel coding and joint source-channel coding of correlated sources
收藏 引用
EURASIP JOURNAL ON APPLIED SIGNAL PROCESSING 2005年 第6期2005卷 942-953页
作者: Zhong, W Garcia-Frias, J Univ Delaware Dept Elect & Comp Engn Newark DE 19716 USA
We propose a coding scheme based on the use of systematic linear codes with low-density generator matrix (LDGM codes) for channel coding and joint source-channel coding of multiterminal correlated binary sources. In b... 详细信息

16th IEEE International Conference on Image Processing
作者: Xiao, Hongjiang Dai, Qionghai Ji, Xiangyang Tsinghua Univ Dept Automat Beijing 100084 Peoples R China
This paper proposes a cooperative multiple-input multiple-output (MIMO) architecture to transmit the video reliably. By exploring the configurable resources of the scalable video and the coded MIMO system, we further ... 详细信息

47th Annual Allerton Conference on Communication, Control, and Computing
作者: Rajesh, R. Sharma, Vinod Indian Inst Sci Dept ECE Bangalore 560012 Karnataka India
In this paper we address the problem of distributed transmission of functions of correlated sources over a fast fading multiple access channel (MAC). This is a basic building block in a hierarchical sensor network use... 详细信息

IEEE TRANSACTIONS ON IMAGE PROCESSING 2009年 第1期18卷 214-216页
作者: Dumitrescu, Sorina McMaster Univ Dept Elect & Comp Engn Hamilton ON L8S 4K1 Canada
In order to prove a key result for their development (Lemma 2), Taubman and Thic need the assumption that the upper boundary of the convex hull of the channel coding probability-redundancy characteristic is sufficient... 详细信息

International Conference on Computer as a Tool (EUROCON 2005)
作者: Lakovic, K Tian, T Villasenor, J Univ Calif Los Angeles Los Angeles CA 90024 USA
We consider joint source-channel coding with variable length codes (VLCs) and LDPC codes. We propose an iterative source-channel decoding system, which involves message passing between a soft-input-soft-output VLC dec... 详细信息

3rd International Workshop on Algorithmic Aspects of Wireless Sensor Networks
作者: Agnihotri, Samar Nuggehalli, Pavan Jamadagni, H. S. Indian Inst Sci CEDT Bangalore 560012 Karnataka India
We consider a single-hop data-gathering sensor network, consisting of a set of sensor nodes that transmit data periodically to a base-station. We are interested in maximizing the lifetime of this network. With our def... 详细信息
