Low-Complexity Linear Equalization for OTFS Systems with Rectangular Waveforms
Wenjun Xu, Tingting Zou, Hui Gao +3
Orthogonal time frequency space (OTFS) is a promising technology for high-mobility wireless communications. However, the equalization realization in practical OTFS systems is a gre…
Low-Complexity Linear Equalizers for OTFS Exploiting Two-Dimensional Fast Fourier Transform
Junqiang Cheng, Hui Gao, Wenjun Xu +2
Orthogonal time frequency space (OTFS) modulation can effectively convert a doubly dispersive channel into an almost non-fading channel in the delay-Doppler domain. However, one cr…
Fixed Region Beamforming using Frequency Diverse Subarray for Secure Mmwave Wireless Communications
Yuanquan Hong, Xiaojun Jing, Hui Gao +1
Millimeter-wave (mmWave) using conventional phased array (CPA) enables highly directional and fixed angular beamforming (FAB), therefore enhancing physical layer security (PLS) in…
Blind Channel Separation in Massive MIMO System under Pilot Spoofing and Jamming Attack
Ruohan Cao, Tan F. Wong, Hui Gao +2
We consider a channel separation approach to counter the pilot attack in a massive MIMO system, where malicious users (MUs) perform pilot spoofing and jamming attack (PSJA) in upli…
