2 × 300 Gbit/s Line Rate PS-64QAM-OFDM THz Photonic-Wireless Transmission
Shi Jia,Lu Zhang,Shiwei Wang,Wei Li,Mengyao Qiao,Zijie Lu,Nazar Muhammad Idrees,Xiaodan Pang,Hao Hu,Xianmin Zhang,Leif Katsuo Oxenløwe,Xianbin Yu +11 more
TL;DR: In this article, a hybrid THz photonic-wireless transmission based on a THz orthogonal polarization dual-antenna scheme is presented, achieving a potential total system throughput of 612.65 Gbit/s with an average net spectral efficiency of 4.445 bit/s/Hz per antenna.

Time variant channel estimation using a modified complex exponential basis expansion model in LTE-OFDM systems
TL;DR: This paper proposes a modification to the well known complex exponential basis expansion model, which is based on the assumed knowledge of the maximum Doppler frequency at the mobile user, to reduce the estimation error up to very high mobile speeds for the OFDMA-based LTE downlink.
Journal ArticleDOI
Photonic Generation and De-Chirping of Broadband THz Linear-Frequency-Modulated Signals
Shiwei Wang,Zijie Lu,Nazar Muhammad Idrees,Shilie Zheng,Xiaofeng Jin,Xianmin Zhang,Xianbin Yu +6 more
TL;DR: In this paper, a coherent photonic superheterodyne based on frequency quadrupling and photo mixing was proposed to generate a 340-380-GHz LFM signal with 40-GHz bandwidth.
Proceedings ArticleDOI
Improving time variant channel estimation for 3GPP LTE-downlink
TL;DR: Simulations show a decrease in MSE when the LMMSE results, obtained at 0dB SNR, are used to track the doubly selective channel at 350 km/h, which is able to reduce the effect of imperfections by shaping the noise at the high frequencies in extended Fixed CE-BEM.
