Space-Air-Ground Integrated Networks: Their Channel Model and Performance Analysis
Chao Zhang, Qingchao Li, Chao Xu +2
Given their extensive geographic coverage, low Earth orbit (LEO) satellites are envisioned to find their way into next-generation (6G) wireless communications. This paper explores…
Space-Time Shift Keying Aided OTFS Modulation for Orthogonal Multiple Access
Zeping Sui, Hongming Zhang, Sumei Sun +2
Space-time shift keying-aided orthogonal time frequency space modulation-based multiple access (STSK-OTFS-MA) is proposed for reliable uplink transmission in high-Doppler scenarios…
Performance Analysis and Approximate Message Passing Detection of Orthogonal Time Sequency Multiplexing Modulation
Zeping Sui, Shefeng Yan, Hongming Zhang +4
In orthogonal time sequency multiplexing (OTSM) modulation, the information symbols are conveyed in the delay-sequency domain upon exploiting the inverse Walsh Hadamard transform (…
Low Complexity Detection of Spatial Modulation Aided OTFS in Doubly-Selective Channels
Zeping Sui, Hongming Zhang, Yu Xin +3
A spatial modulation-aided orthogonal time frequency space (SM-OTFS) scheme is proposed for high-Doppler scenarios, which relies on a low-complexity distance-based detection algori…
MDD-Enabled Two-Tier Terahertz Fronthaul in Indoor Industrial Cell-Free Massive MIMO
Bohan Li, Diego Dupleich, Guoqing Xia +4
To make indoor industrial cell-free massive multiple-input multiple-output (CF-mMIMO) networks free from wired fronthaul, this paper studies a multicarrier-division duplex (MDD)-en…
MARS: Message Passing for Antenna and RF Chain Selection for Hybrid Beamforming in MIMO Communication Systems
Li-Hsiang Shen, Yen-Chun Lo, Kai-Ten Feng +2
In this paper, we consider a prospective receiving hybrid beamforming structure consisting of several radio frequency (RF) chains and abundant antenna elements in multi-input multi…
