| 1 | Covert wireless communication using massive optical comb channels for deep denoising显示文摘Covert wireless communications are unprecedentedly vital for security and privacy of individuals,government,and military bodies.Besides encryption,hiding signal transmission deeply under noise background highly proliferates the covertness in the physical layer.A deep signal hiding leads to a low interception probability at the interceptor but a poor data recovery at the receiver.To ensure both high covertness and high-fidelity recovery,massive and dense optical comb channels are utilized for deep denoising through the analog spectrum convolution.Using an external modulation-based optical frequency comb(OFC)and a single detection branch,the available optical comb channels can sustainably scale up by breaking or greatly mitigating physical bottlenecks on immense hardware and spectrum requirements.Thus,a striking signal-to-noise ratio(SNR)rise can be achieved for deep denoising.Combination of 1024 comb channels(the first parallel comb channel number beyond 1000)and the analog spectrum convolution enable a record SNR enhancement of 29 dB for a microwave signal with a 10.24 GHz bandwidth and a 10 Mbit/s data rate,which is deeply hidden below the in-band noises by 18 dB or even 30 dB in both the frequency and time domains.This method opens a new avenue for covert communications. | XIANGLEI YAN XIHUA ZOU PEIXUAN LI WEI PAN LIANSHAN YAN | 2021 | Photonics Research2021，9，6： | 3 |
| 2 | Covert wireless communication using massive optical comb channels for deep denoising: erratum显示文摘The position of the parentheses in the original manuscript is incorrect.This is a clerical error,and all of the theories and conclusions are unchanged by this correction. | Xianglei Yan Xihua Zou Peixuan Li Wei Pan Lianshan Yan | 2022 | Photonics Research2022，10，2： | 0 |
| 3 | Resilient performance of self-centering hybrid rocking walls with curved interface under pseudo-static loading显示文摘Frame and rocking wall(FRW)structures have excellent resilient performance during earthquakes.However,the concrete at interfacial corners of rocking walls(RWs)is easily crushed due to local extreme compression during the rocking process.An innovative RW with a curved interface is proposed to prevent interfacial corners from producing local damage,enhancing its earthquake resilient performance(ERP).The precast wall panel with a curved interface is assembled into an integral self-centering hybrid rocking wall(SCRW)by two post-tensioned unbonded prestressed tendons.Moreover,two ordinary energy dissipation steel rebars and two shear reinforcements are arranged to increase the energy dissipation capacity and lateral resistance.Two SCRW specimens and one monolithic reinforced concrete(RC)shear wall(SW)were tested under pseudo-static loading to compare the ERPs of the proposed SCRW and the SW,focusing on studying the effect of the curved interface on the SCRW.The key resilient performance of rocking effects,failure modes,and hysteretic properties of the SCRW were explored.The results show that nonlinear deformations of the SCRW are concentrated along the interface between the SCRW and the foundation,avoiding damage within the SCRW.The restoring force provided by the prestressed tendons can effectively realize self-centering capacity with small residual deformation,and the resilient performance of the SCRW is better than that of monolithic SW.In addition,the curved interface of the SCRW makes the rocking center change and move inward,partially relieving the stress concentration and crush of concrete.The rocking range of the rocking center is about 41.4%of the width of the SCRW. | Su Xing Yan Shi Sun Xianglei Wang Tao | 2024 | Earthquake Engineering and Engineering Vibration2024，23，1： | 0 |
