The Guangdong-Hong Kong-Macau Greater Bay Area (GBA) International Workshop on coding and data storage took place on Jun. 18-19, 2022 at the University Town International Hotel in Guangzhou. This workshop was jointly organized by Guangdong University of Technology (GDUT) and the IEEE Information Theory (IT) Society Guangzhou Chapter. Both National Nature Science Foundation of China (NSFC)-Guangdong Joint Fund and GDUT “1+2+3” Discipline Improvement Fund sponsored this workshop. Over 100 researchers participated in the workshop on the day, from over 30 academic institutions or companies including Tsinghua University, Nanjing Univerisy, Sun Yat-sen University, Beihang University, Xinan Jiaotong University, Xidian University, Hangzhou Dianzi University, Huawei Technologies Co., Ltd., Sage Microelectronique Co., Ltd, Shenzhen Longsys Electronics Co. Ltd, DigiCodon Ltd., TenaFe Inc., etc. The workshop was chaired by Dr. Guojun Han, Executive Dean of School of Information Engineering in GDUT, and Dr. Li Chen, Chair of the IT Society Guangzhou Chapter. The organizing committee members include Dr. Yi Fang, Professor of GDUT, Dr. Chang Liu, Associate Professor of GDUT, Dr. Xijun Wang, Associate Professor of Sun Yat-sen University (SYSU), and Dr. Congduan Li, Associate Professor of SYSU.

To keep up with the explosion of data, the next-generation data storage technology must be more practical, economical and reliable than ever before. This workshop aims to provide an opportunity for academic communication on novel progresses regarding the emerging coding methods that are well suited for state-of-the-art data storage systems and bridging the gap between academia and industry in the GBA.

This two-day workshop invited 10 experts to deliver in-depth talks and selected 4 Ph.D. students to deliver oral presentations. It also contains a poster session with 18 student posters. Welcoming speeches were given by Dr. Chengyong Wang, the Vice President of GDUT, Dr. Guojun Han, and Dr. Li Chen.

On the first day, Dr. Xiaohu Tang, Professor of the Xinan Jiaotong University started the morning session by a talk on minimum-storage regenerating (MSR) codes. Then, Dr. Jianjun Luo, Professor of Hangzhou Dianzi University introduced a two-dimensional Turbo Product Code (2D-TPC) algorithm for next generation enterprise-level solid state disk (SSD) controllers. Dr. Liuguo Yin, Professor of Tsinghua University presented generalized sparse codes for non-Gaussian channels. The morning session ended with the talk by Dr. Xiaoyang Zhang, who provided an overview of the development and challenges of erasure coding for current cutting-edge data storage systems. The afternoon session started with the talk delivered by Dr. Zhongfeng Wang, Professor of Nanjing University, presented novel methods for the design and implementation of three kinds of error-correction codes that could be potentially used in storage systems. Then, Dr. Shutao Xia, Professor of Tsinghua University, discussed about Singleton-Optimal constructions of locally repairable codes with small localities. Dr. Qin Huang, Professor of Beihang University, proposed downsampling and transparent coding for blockchain. Dr. Shuo Jiang, a co-founder of DigiCodon Inc., discussed new strategies and methods for DNA data storage. On the second day, Dr. Li Chen started the session with a talk of low-complexity chase decoding of Reed-Solomon codes through modules. The last talk was presented by Dr. Yingquan Wu, chief scientist of TenaFe Inc., who provided a comprehensive perspective of low density parity check code (LDPC) codec for SSD.
