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…

An Improved Diversity Combining Receiver for Layered ACO-FOFDM in IM/DD Systems

Mengqi Guo, Ji Zhou, Xizi Tang +5

In this paper, an improved receiver based on diversity combining is proposed to improve the bit error rate (BER) performance of layered asymmetrically clipped optical fast orthogon…

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…

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…
