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…
Linear MIMO Precoders Design for Finite Alphabet Inputs via Model-Free Training
Chen Cao, Biqian Feng, Yongpeng Wu +2
This paper investigates a novel method for designing linear precoders with finite alphabet inputs based on autoencoders (AE) without the knowledge of the channel model. By model-fr…
LEO Satellite-Enabled Grant-Free Random Access with MIMO-OTFS
Boxiao Shen, Yongpeng Wu, Wenjun Zhang +3
This paper investigates joint channel estimation and device activity detection in the LEO satellite-enabled grant-free random access systems with large differential delay and Doppl…
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…
A Preamble Based MAC Mechanism in Ad-Hoc Network
Chenchao Shi, Biqian Feng, Yongpeng Wu +1
In this paper, we propose a preamble based medium access control (P-MAC) mechanism in Ad-Hoc network. Different from traditional carrier sense multiple access (CSMA) in Ad-Hoc netw…
