Low-Complexity Digital Equalizers for High-Speed Underwater Optical Wireless Communication

Chinese Journal of Electronics 2021年第6期30卷 1167-1172页

作者： LI chao hu Zhijia Information Materials and Intelligent Sensing Laboratory of Anhui Province Institutes of Physical Science and Information Technology Anhui University Information Materials and Intelligent Sensing Laboratory of Anhui Province School of Physics and Materials ScienceAnhui University

hundreds of Megabit per second(Mb/s)data transmission over a moderate range(10 m) underwater optical wireless channel is implemented with 4-level pulse amplitude modulation scheme using an off-the-shelf light-emitting diode as the optical source and digital equalizers. In particular, the channel nonlinear distortion from light-emitting diode is considered and a matched model is developed. To mitigate these distortions under various 4-level pulse amplitude modulation signal baud rates, the Bit error rate(BER) and Signal-to-noise ratio(SNR) performances of the pre-, post-and matchedequalizers are evaluated and compared. The digital matched-equalizer bank is shown and verified to offer the best BER/SNR performance for 4-level pulse amplitude modulation signal using more than 200 MBaud rate. With the proposed equalizer, we have recorded the highest data rate of 600 Mb/s at 20% FEC limit over 10 m free-space underwater link.

Dynamics of cantilever plates and its hybrid vibration control

引用

Acta Mechanica Sinica 2013年第5期29卷 738-748页

作者： Bo Ni chao hu School of Aerospace Engineering and Applied Mechanics Tongji University Shanghai Institute of Spaceflight Fundamental Technology College of Civil Science and Engineering Yangzhou University

Applying Lagrange-Germain＇s theory of elas- tic thin plates and Hamiltonian formulation, the dynamics of cantilever plates and the problem of its vibration control are studied, and a general solution is finally given. Based on Hamiltonian and Lagrangian density function, we can obtain the flexural wave equation of the plate and the relationship between the transverse and the longitudinal eigenvalues. Based on eigenfunction expansion, dispersion equations of propagation mode of cantilever plates are deduced. By satisfying the boundary conditions of cantilever plates, the natural frequencies of the cantilever plate structure can be given. Then, analytic solution of the problem in plate structure is obtained. An hybrid wave/mode control approach, which is based on both independent modal space control and wave control methods, is described and adopted to analyze the active vibration control of cantilever plates. The low-order （controlled by modal control） and the high-order （controlled by wave control） frequency response of plates are both improved. The control spillover is avoided and the robustness of the system is also improved. Finally, simulation results are analyzed and discussed.

The contrast between defect solitons in parity-time symmetric superlattice and simple-lattice complex potentials

引用

Chinese Physics B 2012年第2期21卷 362-367页

作者： hu su-Mei hu Wei Laboratory of Photonic Information Technology South China Normal UniversityGuangzhou 510631China Department of Physics Guangdong University of Petrochemical TechnologyMaoming 525000China

The existence and stability of defect superlattice solitons in parity-time （PT） symmetric superlattice and simplelattice complex potentials are reported. Compared with defect simple-lattice solitons in similar potentials, the defect soliton in superlattice has a wider stable range than that in simple-lattice. The solitons＇ power increases with increasing propagation constant. For the positive defect, the solitons are stable in the whole region where solitons exist in the semi-infinite gap. For the zero defect, the solitons are unstable at the edge of the band. For the negative defect, the solitons propagate with the shape of Y at low propagation constant and propagate stably at the large one.
