Hierarchical Colour-Shift-Keying Aided Layered Video Streaming for the Visible Light Downlink
IEEE Access, 2016 Colour-shift keying (CSK) constitutes an important modulation scheme conceived for the visible light communications (VLC). The signal constellation of CSK relies on three different-color light sources invoked for information transmission.

Novel UEP LT Coding Scheme with Feedback Based on Different Degree Distributions
ITM Web of Conferences, 2016 Traditional unequal error protection (UEP) schemes have some limitations and problems, such as the poor UEP performance of high priority data and the seriously sacrifice of low priority data in decoding property.

Low-Power Cross-Layer Error Management Using MIMO-LDPC Iterative Decoding for Video Processing
IEEE Access, 2021 This paper presents a novel low-power joint decoding system composed of a multiple-input multiple-output (MIMO) detector, low-density parity-check (LDPC) channel decoder, and H.264 source decoder for energy-aware and cross-layer source-channel ...

Research on unequal error protection of irregular LDPC codes
Tongxin xuebao, 2005 An irregular low-density parity-check （LDPC） code with unequal error protection （UEP） property was proposed. A weight-increasing parity-check （WIPC） matrix was constructed.

EFFICIENT MOBILE VIDEO TRANSMISSION BASED ON A JOINT CODING SCHEME
Journal of ICT, 2017 In this paper, we propose a joint coding design which uses the Symbol Forward Error Correction (S-FEC) at the application layer. The purpose of this work is on one hand to minimize the Packet Loss Rate (PLR) and, on the other hand to maximize the visual ...

Rateless Polar-Spinal Coding Scheme With Enhanced Information Unequal Error Protection
IEEE Access, 2019 In this paper, a rateless coding scheme with enhanced unequal error protection (UEP) property is proposed by concatenating the systematic polar code (SPC) and spinal code, where SPC is used as the outer code and spinal code is the inner code.

Adaptive UEP and Packet Size Assignment for Scalable Video Transmission over Burst-Error Channels
EURASIP Journal on Advances in Signal Processing, 2006 This work proposes an adaptive unequal error protection (UEP) and packet size assignment scheme for scalable video transmission over a burst-error channel. An analytic model is developed to evaluate the impact of channel bit error rate on the quality of

Dependency-aware unequal erasure protection codes [PDF]
, 2006 Classical unequal erasure protection schemes split data to be protected into classes which are encoded independently. The unequal protection scheme presented in this paper is based on an erasure code which encodes all the data together according to the ...
