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…
