Pre-equalization Design for ISAC-OTFS Air-Ground Transmission: A Deep Learning Approach
Weihao Wang, Jing Guo, Siqiang Wang +3
Despite the strong Doppler resilience capability, orthogonal time-frequency space (OTFS) modulation suffers from high channel estimation and equalization complexity at the receiver…
Analysis and Optimization of Multiple-STAR-RIS Assisted MIMO-NOMA with GSVD Precoding: An Operator-Valued Free Probability Approach
Siqiang Wang, Zhong Zheng, Jing Guo +2
Among the key enabling 6G techniques, multiple-input multiple-output (MIMO) and non-orthogonal multiple-access (NOMA) play an important role in enhancing the spectral efficiency of…
Mutual Information-oriented ISAC Beamforming Design for Large Dimensional Antenna Array
Shanfeng Xu, Yanshuo Cheng, Siqiang Wang +3
Existing integrated sensing and communication (ISAC) beamforming design were mostly designed under perfect instantaneous channel state information (CSI), limiting their use in prac…
OTFS-based Robust MMSE Precoding Design in Over-the-air Computation
Dongkai Zhou, Jing Guo, Siqiang Wang +4
Over-the-air computation (AirComp), as a data aggregation method that can improve network efficiency by exploiting the superposition characteristics of wireless channels, has recei…
On the Mutual Information of Multi-RIS Assisted MIMO: From Operator-Valued Free Probability Aspect
Zhong Zheng, Siqiang Wang, Zesong Fei +2
The reconfigurable intelligent surface (RIS) is useful to effectively improve the coverage and data rate of end-to-end communications. In contrast to the well-studied coverage-exte…
