Unequal Error Protection in Coded Slotted ALOHA
, 2016 We analyze the performance of coded slotted ALOHA systems for a scenario where users have different error protection requirements and correspondingly can be divided into user classes.

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 ...

Unequal Error Protection QPSK Modulation Codes [PDF]
, 1992 The authors use binary linear UEP (LUEP) codes, in combination with a QPSK signal set and Gray mapping, to obtain new efficient block QPSK modulation codes with unequal minimum squared Euclidean distances.

, 2005 Most multimedia source signals are capable of tolerating lossy, rather than lossless delivery to the human eye, ear and other human sensors. The corresponding lossy and preferably low-delay multimedia source codecs however exhibit unequal error ...

Error Floor Analysis of Coded Slotted ALOHA over Packet Erasure Channels [PDF]
, 2014 We present a framework for the analysis of the error floor of coded slotted ALOHA (CSA) for finite frame lengths over the packet erasure channel. The error floor is caused by stopping sets in the corresponding bipartite graph, whose enumeration is, in ...

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.

Aging and Cancer, EarlyView.ABSTRACT As global populations age, cancer is increasingly becoming a leading cause of morbidity and mortality among older adults, particularly in low‐ and middle‐income countries (LMICs). Despite accounting for the majority of new cancer cases and deaths, older individuals remain underrepresented in cancer research, clinical guidelines, and health ...

Error-Resilient Unequal Error Protection of Fine Granularity Scalable Video Bitstreams
EURASIP Journal on Advances in Signal Processing, 2006 This paper deals with the optimal packet loss protection issue for streaming the fine granularity scalable (FGS) video bitstreams over IP networks. Unlike many other existing protection schemes, we develop an error-resilient unequal error protection (ER-

Application of convolutional interleavers in turbo codes with unequal error protection
Journal of Telecommunications and Information Technology, 2006 This paper deals with an application of convolu- tional interleavers in unequal error protection (UEP) turbo codes. The constructed convolutional interleavers act as block interleavers by inserting a number of stuff bits into the interleaver memories at
