Design of Encoding Algorithm for Underwater Wireless Optical Communication Based on Spinal Code

Journal of Marine Science and Engineering
The marine environment is complex and variable, with the absorption and scattering effects of seawater and turbulence causing significant attenuation of received optical signals and introducing random jitter, which limits the communication range and ...

2001 IEEE Information Theory Workshop (ITW'01) [PDF]

, 2001
An investigation of unequal error protection (UEP) methods applied to JPEG image transmission using turbo codes is presented. The JPEG image is partitioned into two groups, i.e., DC components and AC components according to their respective sensitivity ...

Rate-Distortion Optimization for Stereoscopic Video Streaming with Unequal Error Protection

EURASIP Journal on Advances in Signal Processing, 2008
We consider an error-resilient stereoscopic streaming system that uses an H.264-based multiview video codec and a rateless Raptor code for recovery from packet losses. One aim of the present work is to suggest a heuristic methodology for modeling the end-

Canonical convolutional encoders for unequal error protection

, 2012
[[abstract]]In this paper, canonical convolutional encoders are studied for unequal error protection (UEP) from an algebraic theoretical viewpoint. We show that for any convolutional code there exists at least a canonical generator matrix which has the ...

Polar codes with the unequal error protection property

, 2018
The Internet of Things (IoT) is expected to support a wide variety of devices with different transmission reliability requirements. Channel codes with the unequal error protection (UEP) property are rather appealing for such applications.

Multilevel Block Coded Modulation with Unequal Error Protection [PDF]

, 1997
Multilevel block coded modulation (BCM) schemes with unequal error protection (UEP) are investigated. These schemes are based on unconventional set partitions that greatly reduce the error coefficients associated with multi-stage decoding of conventional

Turbo-Detected Unequal Error Protection Irregular Convolutional Codes Designed for the Wideband Advanced Multirate Speech Codec

, 2005
—since the different bits of multimedia information, such as speech and video, have different error sensitivity, efficient unequalprotection channel coding schemes have to be used to ensure that the perceptually more important bits benefit from more ...

A novel unequal error protection scheme for 3-D video transmission over cooperative MIMO-OFDM systems [PDF]

, 2012
Currently, there has been intensive research to drive three-dimensional (3-D) video technology over mobile devices. Most recently, multi-input multi-output (MIMO) with orthogonal frequency division multiplexing (OFDM) and cooperative diversity have been ...
