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…
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…
Faster-than-Nyquist Non-Orthogonal Frequency-Division Multiplexing for Visible Light Communications
Ji Zhou, Yaojun Qiao, Tiantian Zhang +6
In this paper, we propose a faster-than-Nyquist (FTN) non-orthogonal frequency-division multiplexing (NOFDM) scheme for visible light communications (VLC) where the multiplexing/de…
Capacity limit for faster-than-Nyquist non-orthogonal frequency-division multiplexing signaling
Ji Zhou, Yaojun Qiao, Zhanyu Yang +2
Faster-than-Nyquist (FTN) signal achieves higher spectral efficiency and capacity compared to Nyquist signal due to its smaller pulse interval or narrower subcarrier spacing. Shann…
