Uncoordinated multiuser/MIMO channel estimation using superimposed training by Chun-quan HE, Gao-qi DOU, Jun GAO, Gao-ming HUANG

“…An iterative channel estimation and detection scheme is proposed for single carrier uncoordinated multi-user/multi-input multi-output (MIMO) system using superimposed training (ST). At first, the multiple antennas mutual interferences are eliminated by utilizing training sequences with all-zero cross-correlation property, which are designed based on transform domain approach. …”

Study on Transmission Error of Cylindrical Gear with Arcuate Tooth Trace by Ma Dengqiu, Ye Zhenhuan, An Yu, Wu Tingqiang, Chen Fangzhou

“…In order to study the transmission error of the cylindrical gear with arcuate tooth trace，a torsional vibration model of the cylindrical gear with arcuate tooth trace transmission system is proposed，and a dynamics model is established based on 3D model.The influence of tooth width，tooth line radius，load and rotation speed on the transmission error is analyzed.The results show that，the transmission error fluctuates periodically around 0 when the structure parameters and working conditions are different； the transmission error amplitude decreases first and then increases with the increase of the tooth width； the transmission error amplitude changes in shape of “W” with the increase of the tooth line radius，that is，it first decreases and then increases with the increase of the tooth line radius，and then first decreases and then increases with the increase of the tooth line radius； the transmission error amplitude increases with the increase of load and rotating speed.The results provide the theoretical basis for the noise reduction and lubrication，fault diagnosis and gear tooth geometric modification of the cylindrical gear with arcuate tooth trace.…”

Intelligent prediction method of network performance based on graph neural network by Yijiang LI, Huibiao YE, Renhua XIE, Jiali LOU, Danna ZHUANG, Chuanhuang LI

“…There are some problems in the traditional network performance prediction technology, such as incomplete network state acquisition and poor accuracy of network performance evaluation.Combined with the characteristics of graph neural network learning and reasoning network relational data and the captured global information of the network, on the basis of the current network performance prediction methods, an intelligent prediction method of network performance based on graph neural network was proposed.Aiming at the complex network information, through the research of network system abstraction and network performance modeling, the network information can be transformed into the graph space convolution was used to process the message passing process of graph network nodes to realize the relationship reasoning between network information.The graph neural network model for network performance prediction was studied, and a graph neural network architecture which could deal with traffic matrix, network topology, routing strategy and node configuration was proposed.Finally, the experiments show that the model can better achieve accurate prediction of the network performance including delay, jitter and packet loss rate.…”
