Trends and enabling technologies on high-speed metro and short-reach optical transmission systems by Lei ZHANG, Yixiao ZHU, Fan ZHANG, Zhangyuan CHEN

“…The optical fiber communication network is the important infrastructure for the modern information society.Thanks to the reduction of fiber loss,the improvement of transceiver devices by electro-optical-electrical conversion,the development of modulation technology and the introduction of digital signal processing,the capacity of optical fiber transmission has been greatly improved.In recent years,due to the large capacity demand of data-centers and the next-generation wireless communication,metro and short-range transmission scenarios below 100 km have attracted lots of attention based on direct detection.The historical evolution of optical fiber communication systems was firstly reviewed,then the limiting factors in the direct detection system were analyzed.Furthermore,the principle and system configuration of one-dimensional to four-dimensional self-coherent technology were introduced,and finally,the low-cost evolution trend of the optical coherent transmission system was prospected.…”

Indoor Wi-Fi fingerprint localization method based on CSI tensor decomposition by Mu ZHOU, Yuexin LONG, Qiaolin PU, Yong WANG, Wei HE

“…Aiming at the problem that as the scale of the fingerprint database increases, the training cost and processing complexity of CSI fingerprints will also greatly increase, an indoor Wi-Fi fingerprint localization method based on CSI tensor decomposition was proposed.Firstly, the tensor decomposition algorithm based on the PARAFAC (parallel factor) analysis model and the ALS (alternate least squares) iterative algorithm were combined to reduce the interference of the environment.Then, the tensor wavelet decomposition algorithm was used to extract the feature and obtain the CSI fingerprint.Finally, a localization model was established based on the PLSR (partial least squares regression) algorithm to realize the location estimation.Experimental results show that the confidence probability of the proposed method is 94.88% within 4 m localization error, which verifies that the proposed method has good localization performance while fitting the relationship between CSI location fingerprints and location coordinates.…”

ANALYSIS OF SHEARER VIBRATION CHARACTERISTICS UNDER DIFFERENT LIFT ANGLE by MAO Jun, YANG XinWei, SONG QiuShuang

“…According to shearer vibration problems in the practical work,using multi-body dynamics theory,considering shearer support characteristics of guide boots and flat boots,and the stiffness of rocker arm and adjustment height oil vat,6 degrees of freedom dynamic model in the vertical direction of shearer was established.The vertical direction of shearer drum load was used as an external excitation,and the effect of different lift angle on vertical direction vibration characteristics of shearer were solved by using numerical analysis method.The results show that the lift angle has great influence on vibration displacement of drum and ranging arm when the range is 17° 37°,and the displacement range is 21.5521 15.424 mm,9.4005 ~3.306 4 mm.Because of the low frequency vibration of shearer under actual operating conditions,the vibration acceleration under different lift angle is insensitive.…”

Novel opportunistic cooperative multicast scheme for NOMA by Yin LU, Jirong CHEN, Haowei BIAN, Hongbo ZHU

“…The cognitive radio technology was applied to non-orthogonal multiple access (NOMA) cooperative multicast system,the feasibility of using users as relays was studied,and a two-level cooperative transmission scheme with parameterized multicast candidate sets was proposed.Specifically,the scheme first selected the candidate set according to the cardinality q,and then selected the best forwarding node based on the channel gain between the primary users and the candidate secondary users.Simulation results show that,through the reasonable selection of the cardinality q,the proposed scheme can greatly reduce the diversity gain of the secondary users while simultaneously increasing the diversity gain of the primary users.In NOMA cooperative multicast scenario composed of N multicast users,the proposed scheme can increase the diversity gain of the primary users from 2 to min(N-q+2,q+1) to meet their reliability requirements.…”
