Performance comparison of systematic polar code and non-systematic polar code by Hui LI, Ming YE, Qiang TONG, Jie CHENG, Lijie WANG

“…Polar code in channel coding schemes is a research hotspot in 5G communication field.Polar code is susceptible to error propagation under successive cancellation decoding,and the performance of the code at short and medium block lengths is not ideal.For the problems,the performance difference between systematic polar code and non-systematic polar code was studied under various simulation conditions.Simulation results demonstrate that systematic polar code has advantage over non-systematic polar code in bit error rate performance,and the former are more robust against error propagation than the latter under successive cancellation decoding.The above results are considerable importance from the theoretical values in 5G communication and performance optimization of polar code.…”

Study on the Dynamics Characteristic of Helical Gear with Tooth Profile Deviation by Zhang Yanjie, Wu Xuncheng, Zhang Juecheng

“…For study the impact of the tooth profile total deviation on the dynamics characteristic of helical gear,based on theoretical involute and tooth profile total deviation value,the mathematical model of error involute with tooth profile deviation is established.By taking a involute helical gear pair as the research object,the 3D model of helical gear pair with tooth profile deviation is established by using UG,and the reliability of the ideal model is verified by using ADAMS.Meanwhile,combining the ANSYS,the angular velocity,angular acceleration of driven gear of the error model and ideal model are compared and analyzed.The results show that the conclusion in dynamics simulation based on ADAMS is the nearly same as transient kinetic analysis based on ANSYS.The tooth profile deviation has significant effect on the angular velocity and angular acceleration of driven gear.…”
