Optimized Puncturing for the Spinal Codes
ICC 2019 - 2019 IEEE International Conference on Communications (ICC), 2019As a type of newly invented rateless codes, Spinal codes can achieve the capacity of both additive white Gaussian noise (AWGN) channel and binary symmetric channel (BSC) with short message length and pseudo-random like codewords. In this paper, a novel puncturing pattern called inverted triangle-shaped puncturing is proposed for Spinal codes.

Performance of spinal codes with sliding window decoding
2017 IEEE International Symposium on Information Theory (ISIT), 2017In this paper, we focus on the finite-length performance of spinal codes with a sliding window decoder over binary erasure channel. An expression of the error probability of spinal codes is derived. Particularly, we also derive an expression of the error probability of spinal codes with some known tail bits, which can improve the error-control ...

Design and performance of spinal codes over fading channels
2014 International Workshop on High Mobility Wireless Communications, 2014Spinal codes are a new kind of rateless codes designed for noisy channels. In this paper, we will explore the design and performance of spinal codes on rapidly time-varying channels, which corresponds to high mobility scenarios, and propose a parallel coding scheme to improve their performance in terms of Bit-Error-Ratio (BER) and spectral-efficiency ...

A Study on Transmission Efficiency of Systematic Spinal Codes
2019 Seventh International Symposium on Computing and Networking Workshops (CANDARW), 2019A spinal code is one of promising rate-less code by combining forward error collection with automatic repeat-request. In the decoding of the spinal code, a collision of codewords may degrade the transmission efficiency. The systematic coded spinal code can improve the transmission efficiency because of the avoidance of the collision of the codewords ...

A novel spinal codes based on chaotic Kent mapping
2019 IEEE/CIC International Conference on Communications Workshops in China (ICCC Workshops), 2019Spinal codes are a new class of rateless codes that can achieve the channel capacity over time-varying channel condition. Pseudo random hash function is the core of spinal codes, which is executed to generate spines in every encoding and decoding process. However, due to the complexity of hash function, the decoding of spinal codes is complicated.

Design and Analysis of Unequal Error Protection Rateless Spinal Codes
IEEE Transactions on Communications, 2016In this paper, we propose and analyze an unequal error protection (UEP) rateless spinal code, which can provide UEP and unequal recovery time properties. The proposed UEP spinal codes achieve UEP by the permutation of different priority levels and the setup of different segment sizes for different priority levels.

A Low Complexity Sequential Decoding Algorithm for Rateless Spinal Codes
IEEE Communications Letters, 2015A forward stack decoding (FSD) algorithm for rateless spinal codes is proposed in this letter. This decoding algorithm divides the decoding tree of the spinal code into several layers, and then searches the decoding paths in each single layer. Compared with the bubble decoder, which was initially designed for spinal codes, the proposed FSD algorithm ...

Non-coding RNAs in ossification of spinal ligament
European Spine Journal, 2021Ossification of the spinal ligament (OSL) is a disease characterized by progressive ectopic ossification or calcification in the tissues of spinal ligament. The molecular pathogenesis of OSL has not been clearly elucidated. Recently, ncRNAs was found to functionally participate in OSL development.

The Smart Computing Review, 2013
Spinal codes are a new kind of adaptive rateless codes. By analyzing the theory, consisting of hash-function encoding, modulation, maximum-likelihood decoding, and puncturing, the data structure was redesigned, and simulation of the whole transmission process was accomplished. The transfer rate was tested with both additive white Gaussian noise channel
