PMDS Array Codes With Small Sub-packetization, Small Repair Bandwidth/Rebuilding Access
Jie Li, Xiaohu Tang, Hanxu Hou +3
Partial maximum distance separable (PMDS) codes are a kind of erasure codes where the nodes are divided into multiple groups with each forming an MDS code with a smaller code lengt…
A Linear Time Algorithm for the Optimal Discrete IRS Beamforming
Shuyi Ren, Kaiming Shen, Xin Li +2
It remains an open problem to find the optimal configuration of phase shifts under the discrete constraint for intelligent reflecting surface (IRS) in polynomial time. The above pr…
A Codebook Design for FD-MIMO Systems with Multi-Panel Array
Zhilin Fu, Sangwon Hwang, Jihwan Moon +2
In this work, we study codebook designs for full-dimension multiple-input multiple-output (FD-MIMO) systems with a multi-panel array (MPA). We propose novel codebooks which allow p…
New Decoding of Reed-Solomon Codes Based on FFT and Modular Approach
Nianqi Tang, Yunghsiang S. Han
Decoding algorithms for Reed--Solomon (RS) codes are of great interest for both practical and theoretical reasons. In this paper, an efficient algorithm, called the modular approac…
Constellation Design for Deep Joint Source-Channel Coding
Mengyang Wang, Jiahui Li, Mengyao Ma +1
Deep learning-based joint source-channel coding (JSCC) has shown excellent performance in image and feature transmission. However, the output values of the JSCC encoder are continu…
Cooperative Reflection and Synchronization Design for Distributed Multiple-RIS Communications
Yaqiong Zhao, Wei Xu, Xiaohu You +2
To reap the promised gain achieved by distributed reconfigurable intelligent surfaces (RISs)-enhanced communications in a wireless network, timing synchronization among these metas…
