Error and Congestion Resilient Video Streaming over Broadband Wireless

open access: yesComputers, 2015
In this paper, error resilience is achieved by adaptive, application-layer rateless channel coding, which is used to protect H.264/Advanced Video Coding (AVC) codec data-partitioned videos.

CRC-aided Multiple Traceback Decoding Algorithm of Spinal Code [PDF]

open access: yesJisuanji gongcheng, 2017
In order to improve the decoding efficiency of Spinal code,the beam search and Cyclic Redundancy Check(CRC)decoding are considered as a whole for joint decoding,a CRC-aided multiple traceback decoding algorithm is proposed.The correct decoding route is ...

Augmented LT codes over binary extension fields with increased ratio of full‐degree columns

open access: yesElectronics Letters, Volume 60, Issue 5, March 2024.
An augmented scheme of LT codes is proposed to improve the decoding success rate. The method involves substituting the 1 in full‐degree columns of the generator matrix of conventional LT codes with binary extension field elements and simultaneously increasing the ratio of full‐degree columns in the ideal soliton distribution, which allows for higher ...

Rateless Multiple Access: Asymptotic Throughput Analysis and Improvement With Spatial Coupling

open access: yesIEEE Access, 2018
A novel random code-domain non-orthogonal multiple access (NOMA) framework, rateless multiple access (RMA), is studied in this paper. In RMA, instead of granting each user specific radio resources in a fixed and centralized manner, the access point ...

Throughput of Rateless Codes Over Broadcast Erasure Channels [PDF]

open access: yesIEEE/ACM Transactions on Networking, 2012
In this paper, we characterize the throughput of a broadcast network with n receivers using rateless codes with block size K. We assume that the underlying channel is a Markov modulated erasure channel that is i.i.d. across users, but can be correlated in time. We characterize the system throughput asymptotically in n.

HARQ‐Chaotic: Analog Chaotic Code Applied in HARQ Scheme of Wireless Communication System

open access: yesWireless Communications and Mobile Computing, Volume 2019, Issue 1, 2019., 2019
This paper proposes a novel symbol‐level combining hybrid automatic repeat request (HARQ) scheme based on analog chaotic code and named HARQ‐Chaotic. The transmitter of HARQ‐Chaotic adopts analog chaotic code to encode Quadrature Amplitude Modulation (QAM) symbols of retransmission packets to combat fading and noise. As the analog chaotic code can only

Design and Analysis of LT Codes with Decreasing Ripple Size

open access: yes, 2012
In this paper we propose a new design of LT codes, which decreases the amount of necessary overhead in comparison to existing designs. The design focuses on a parameter of the LT decoding process called the ripple size.

Near-Capacity Adaptive Analog Fountain Codes for Wireless Channels

open access: yes, 2013
In this paper, we propose a capacity-approaching analog fountain code (AFC) for wireless channels. In AFC, the number of generated coded symbols is potentially limitless.

Fountain Codes with Nonuniform Selection Distributions through Feedback

open access: yes, 2015
One key requirement for fountain (rateless) coding schemes is to achieve a high intermediate symbol recovery rate. Recent coding schemes have incorporated the use of a feedback channel to improve intermediate performance of traditional rateless codes ...

Rateless-Coding-Assisted Multi-Packet Spreading over Mobile Networks

open access: yes, 2014
A novel Rateless-coding-assisted Multi-Packet Relaying (RMPR) protocol is proposed for large-size data spreading in mobile wireless networks. With this lightweight and robust protocol, the packet redundancy is reduced by a factor of $\sqrt n$, while the ...
