High spectral efficiency SSB-PAM-DD scheme with high linewidth tolerance by Dongxu LU, Xian ZHOU, Fei LIU, Jiahao HUO, Jinhui YUAN, Keping LONG

“…For low-cost and high chromatic dispersion (CD) robustness single sideband (SSB) with direct detection (DD), three schemes of SSB with pulse amplitude modulation (PAM) were investigated.Among that, the highest spectral efficiency was achieved by the scheme of adding the frequency down-conversion at the transmitter.However, that scheme reduces the tolerance for laser linewidth.Hence, based on the character of the SSB-PAM signal, a DSP scheme was proposed, including a modified equalization algorithm with phase distortion immunity and blind phase search algorithm.The simulation results show that the modified scheme can tolerate 1 MHz linewidth for 112 Gbit/s SSB-PAM-DD, while the original scheme for SSB-PAM was only 100 kHz at the same bit error rate (BER) threshold.Therefore, the proposed scheme can achieve a high frequency efficiency, high linewidth tolerance, and low-cost SSB-PAM signaling transmission.…”

Backscatter communication assisted vehicular positioning technology with ultra-high accuracy by Kaifeng HAN, Tiezhi LIU

“…The accurate vehicular positioning technology has been the fundamentalfunction for safer auto-driving and vehicular-to-everything networks.One research trend focuses on enabling the low-cost,reliable,and accurate vehicular positioning in high-density cities,tunnels,and underground where the GPS or cellular positioning can’t work due to the signaling blocking.To this end,a novel backscatter communication assisted vehicular positioning system was proposed where a backscatter-reader (with two antennas) was deployed on vehicle and at least one backscatter-tag is deployed along a roadside,based on which the location of vehicle could be estimated with ultra-high reliability and accuracy.Through simulation verification,BackCom vehicle positioning technology can achieve extremely high positioning accuracy.At the same time,BackCom’s vehicle positioning technology is very easy to expand.By increasing the number of antennas in its positioning reader,it could further improve its positioning accuracy.BackCom vehicle positioning technology has the advantages of low cost,low power consumption,high accuracy,high reliability,and easy deployment.It is suitable for various driving environments and has extremely high theoretical research value and commercial value.…”
