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…

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…

Sphere Decoder with Box Optimization for FTN Non-orthogonal FDM System
Mengqi Guo, Ji Zhou, Yueming Lu +1
In 1975, the pioneering work of J. E. Mazo showed the potential faster-than-Nyquist (FTN) gain of single-carrier binary signal. If the inter-symbol interference is eliminated by an…
