Construction and Design of MPAC Codes
Fangbo Yi, Zuoxin Cai, Zhongjun Yang +4
This paper proposes modified polarization-adjusted convolutional (MPAC) codes and their hybrid decoding that achieves an improved performance-complexity tradeoff. For MPAC codes, o…
Perturbation Power Selection for First-Error Delay Maximization in Enhanced SC Decoding
Zhicheng Liu, Liuquan Yao, Shuai Yuan +5
In this paper, we analyze the effect of perturbation power in delaying the first error position, i.e., the first information bit incorrectly decoded by the successive cancellation…
GII-Polar Codes for Block Fading Channels
Fangbo Yi, Zhongjun Yang, Xinzheng He +2
Polar codes are proven to be capacity-achieving codes, being gradually practiced in wireless communications. However, their successive cancellation (SC) and successive cancellation…
SCL Decoding of Non-Binary Linear Block Codes
Jingyu Lin, Li Chen, Xiaoqian Ye
Non-binary linear block codes (NB-LBCs) are an important class of error-correcting codes that are especially competent in correcting burst errors. They have broad applications in m…
Design of Coded Caching Schemes with Linear Subpacketizations Based on Injective Arc Coloring of Regular Digraphs
Xianzhang Wu, Minquan Cheng, Li Chen +2
Coded caching is an effective technique to decongest the amount of traffic in the backhaul link. In such a scheme, each file hosted in the server is divided into a number of packet…
Design of Placement Delivery Arrays for Coded Caching with Small Subpacketizations and Flexible Memory Sizes
Xianzhang Wu, Minquan Cheng, Congduan Li +1
Coded caching is an emerging technique to reduce the data transmission load during the peak-traffic times. In such a scheme, each file in the data center or library is usually divi…
