Reduced-Complexity Cross-Domain Iterative Detection for OTFS Modulation via Delay-Doppler Decoupling
Mengmeng Liu, Shuangyang Li, Baoming Bai +1
In this paper, a reduced-complexity cross-domain iterative detection for orthogonal time frequency space (OTFS) modulation is proposed, which exploits channel properties in both ti…
Matroidal Entropy Functions: Constructions, Characterizations and Representations
Qi Chen, Minquan Cheng, Baoming Bai
Matroidal entropy functions are entropy functions in the form , where is an integer and is the rank function of a…
On the Pulse Shaping for Delay-Doppler Communications
Shuangyang Li, Weijie Yuan, Zhiqiang Wei +3
In this paper, we study the pulse shaping for delay-Doppler (DD) communications. We start with constructing a basis function in the DD domain following the properties of the Zak tr…
Faster-than-Nyquist Asynchronous NOMA Outperforms Synchronous NOMA
Shuangyang Li, Zhiqiang Wei, Weijie Yuan +4
Faster-than-Nyquist (FTN) signaling aided non-orthogonal multiple access (NOMA) is conceived and its achievable rate is quantified in the presence of random link delays of the diff…
A Novel ISAC Transmission Framework based on Spatially-Spread Orthogonal Time Frequency Space Modulation
Shuangyang Li, Weijie Yuan, Chang Liu +4
In this paper, we propose a novel integrated sensing and communication (ISAC) transmission framework based on the spatially-spread orthogonal time frequency space (SS-OTFS) modulat…
Hybrid MAP and PIC Detection for OTFS Modulation
Shuangyang Li, Weijie Yuan, Zhiqiang Wei +4
Orthogonal time frequency space (OTFS) modulation has attracted substantial attention recently due to its great potential of providing reliable communications in high-mobility scen…
