Excess Distortion Exponent Analysis for Semantic-Aware MIMO Communication Systems
Yuxuan Shi, Shuo Shao, Yongpeng Wu +3
In this paper, the analysis of excess distortion exponent for joint source-channel coding (JSCC) in semantic-aware communication systems is presented. By introducing an unobservabl…
Symbol-wise Puncturing for HARQ Integration with Probabilistic Amplitude Shaping
Li Shen, Yongpeng Wu, Derrick Wing Kwan Ng +2
In this letter, we propose a symbol-wise puncturing scheme to support hybrid automatic repeat request (HARQ) integrated probabilistic amplitude shaping (PAS). To prevent the probab…
Joint Device Detection, Channel Estimation, and Data Decoding with Collision Resolution for MIMO Massive Unsourced Random Access
Tianya Li, Yongpeng Wu, Mengfan Zheng +5
In this paper, we investigate a joint device activity detection (DAD), channel estimation (CE), and data decoding (DD) algorithm for multiple-input multiple-output (MIMO) massive u…
Optimization Techniques in Reconfigurable Intelligent Surface Aided Networks
Biqian Feng, Junyuan Gao, Yongpeng Wu +3
Reconfigurable intelligent surface (RIS)-aided networks have been investigated for the purpose of improving the system performance. However, the introduced unit modulus phase shift…
Omnidirectional Space-Time Block Coding for Common Information Broadcasting in Massive MIMO Systems
Xin Meng, Xiang-Gen Xia, Xiqi Gao
In this paper, we design space-time block codes (STBCs) to broadcast the common information omnidirectionally in a massive MIMO downlink. To reduce the burden of the downlink chann…
Error Correction in Polynomial Remainder Codes with Non-Pairwise Coprime Moduli and Robust Chinese Remainder Theorem for Polynomials
Li Xiao, Xiang-Gen Xia
This paper investigates polynomial remainder codes with non-pairwise coprime moduli. We first consider a robust reconstruction problem for polynomials from erroneous residues when…
