Code-Aided Channel Estimation in LDPC-Coded MIMO Systems
Binghui Shi, Yongpeng Wu, Peihong Yuan +3
For a multiple-input multiple-output (MIMO) system with unknown channel state information (CSI), a novel low-density parity check (LDPC)-coded transmission (LCT) scheme with joint…
R-PMAC: A Robust Preamble Based MAC Mechanism Applied in Industrial Internet of Things
Kai Song, Biqian Feng, Yongpeng Wu +2
This paper proposes a novel media access control (MAC) mechanism, called the robust preamble-based MAC mechanism (R-PMAC), which can be applied to power line communication (PLC) ne…
Proactive Content Caching Scheme in Urban Vehicular Networks
Biqian Feng, Chenyuan Feng, Daquan Feng +2
Stream media content caching is a key enabling technology to promote the value chain of future urban vehicular networks. Nevertheless, the high mobility of vehicles, intermittency…
Energy Efficiency of MIMO Massive Unsourced Random Access with Finite Blocklength
Junyuan Gao, Yongpeng Wu, Tianya Li +1
This paper investigates the energy efficiency of massive unsourced random access~(URA) in multiple-input multiple-output quasi-static Rayleigh fading channels. Specifically, we der…
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…
