Hybrid precoding method for millimeter-wave massive MIMO systems based on IAFS algorithm by Haoyi CHEN, Guangqiu LI, Hui LI

“…The millimeter-wave massive multiple-input multiple-output (MIMO) systems can overcome the adverse effects of the free-space signal path loss through the partial connection hybrid precoding method, which has the advantages of low hardware complexity and high energy efficiency.When the number of input data streams is equal to the number of radio frequency (RF) links, the hybrid precoding method based on partially connected structure and serial interference cancellation can be used.When the number of input data streams is not equal to the number of RF links, a hybrid precoding method based on improved artificial fish swarm (IAFS) algorithm was proposed.The core idea is that based on the spectral efficiency optimization criteria and the characteristics of partial connected structure, the spectral efficiency optimization problem of analog recoding matrix variables was transformed into the spectral efficiency optimization problem based on vector variables, and then the IAFS algorithm was used to solve the spectrum efficiency optimization problem.The simulation results show that the proposed method has good spectral efficiency and energy efficiency under the condition of low signal-to-noise ratio, and is expected to be applied in the real scene.…”

Study on the mechanical properties of negative poisson’s ratio honeycomb prepared by equibiaxial compression method by LI Yuwei, SU Buyun, QIU Ji, SHU Xuefeng, LI Zhiqiang

“…ObjectiveNegative Poisson’s ratio materials are widely used in various fields because of their unique properties of expansion in tension and contraction in compression.MethodsA honeycomb material with negative Poisson’s ratio was obtained by equal biaxial compression of the two-dimensional Voronoi model, and the effects of different compression ratios on its static tensile/compressive mechanical properties were studied by numerical simulation.ResultsThe results show that the tensile and compressive stress-strain curves of the two-dimensional negative Poisson’s ratio honeycomb prepared by the above method have typical "three-stage" deformation characteristics of porous materials, and show significant tensile and compressive strength asymmetry. …”
