New research on unequal error protection (UEP) property of irregular LDPC codes

2003 International Symposium on VLSI Technology, Systems and Applications. Proceedings of Technical Papers. (IEEE Cat. No.03TH8672), 2004
A new scheme is proposed about how to make use of the unequal error protection (UEP) property of irregular low-density parity-check (LDPC) codes. By means of the construction of a weight-increasing parity-check matrix and systematic encoding, the mapping between the important information data and the elite bits of an irregular LDPC code becomes ...

Efficient QoS control using unequal error protection (UEP) in physical layer

Vehicular Technology Conference. IEEE 55th Vehicular Technology Conference. VTC Spring 2002 (Cat. No.02CH37367), 2003
A new concept of unequal error protection (UEP) in the physical layer of a mobile cellular communication system is presented. With various potential extensible schemes of the proposed scheme, UEP for multiple applications having different QoS requirements (ftp type best effort application and video streaming type near-real time application are used for

Unequal Error Protection (UEP) for Wavelet-Based Wireless 3D Mesh Transmission

2009 Eighth IEEE International Symposium on Network Computing and Applications, 2009
The recent popularity of networked graphicsapplications such as distributed military simulators andonline games, has increased the need to transmit large 3Dmeshes and textures over wireless networks. To speed up large mesh transmission over low-bandwidth wireless links, we use a wavelet-based technique that aggressively compresses large meshes and ...

A New Approach in Digital Image Compression Using Unequal Error Protection (UEP)

Applied Mechanics and Materials, 2014
This paper proposes a new algorithms for compression of digital images especially at the encoding stage of compressive sensing. The research consider the fact that a certain region of a given imagery is more important in most applications. The first algorithm proposed for the encoding stage of Compressive Sensing (CS) exploits the known structure of ...

Unequal error protection (UEP) of wavelet coded video using multi-layered Hierarchical QAM

2011 International Conference on Multimedia, Signal Processing and Communication Technologies, 2011
In this paper, the performance of unequal error protection (UEP) scheme for wavelet coded video using multi-layered 64-Hierarchical QAM (64-HQAM) is presented. Depending on the error sensitivity of coded video bitstream against channel errors, the bitstream is partitioned into multiple sub-streams.
