Fast Transceiver Design for RIS-Assisted MIMO mmWave Wireless Communications
Haiyue Jing, Wenchi Cheng, Xiang-Gen Xia
Due to high bandwidth and small antenna size, millimeter-wave (mmWave) integrated line-of-sight (LOS) multiple-input-multiple-output (MIMO) systems have attracted much attention. R…
Discrete Spectrum Analysis of Vector OFDM Signals
Xiang-Gen Xia, Wei Wang
Vector OFDM (VOFDM) is equivalent to OTFS and is good for time-varying channels. However, due to its vector form, its signal spectrum is not as clear as that of the conventional OF…
Delay Doppler Transform
Xiang-Gen Xia
This letter is to introduce delay Doppler transform (DDT) for a time domain signal. It is motivated by the recent studies in wireless communications over delay Doppler channels tha…
Robust Multidimentional Chinese Remainder Theorem for Integer Vector Reconstruction
Li Xiao, Haiye Huo, Xiang-Gen Xia
The problem of robustly reconstructing an integer vector from its erroneous remainders appears in many applications in the field of multidimensional (MD) signal processing. To addr…
3-D Positioning and Resource Allocation for Multi-UAV Base Stations Under Blockage-Aware Channel Model
Pengfei Yi, Lipeng Zhu, Zhenyu Xiao +3
In this paper, we propose to deploy multiple unmanned aerial vehicle (UAV) mounted base stations to serve ground users in outdoor environments with obstacles. In particular, the ge…
