Massive MIMO LEO Satellite Communications System by Kexin LI, Li YOU, Xiqi GAO

“…Extending massive multiple-input multiple-output (MIMO) technique to low earth orbit (LEO) satellite communication systems enables satellites to implement fl exible beamforming, which can make full use of the spatial degrees of freedom of massive MIMO and signifi cantly improve the spectral effi ciency and energy effi ciency of LEO satellite communication systems.Several related issues in massive MIMO-based LEO satellite communication systems were studied.The characteristics of massive MIMO LEO satellite channels were analyzed.The important diff erences between them and terrestrial wireless channels were revealed.With the aim of addressing the problems on channel information acquisition, multi-user transmission and user scheduling in massive MIMO LEO satellite communication, the main difficulties faced by the current work were discussed, and how to use the characteristics of massive MIMO LEO satellite channels to design tailored solutions with low implement complexity was conceived.…”

Discussions about application of blockchain in IoT systems by Zhen GAO, Qimei CUI, Xuefei ZHANG, Xiaofei WANG

“…Blockchain technology has attracted wide attention in recent years,and many industries are trying to solve the reliability and security problems of traditional centralized schemes in information systems based on blockchain technology.However,the connection between the blockchain network and industry entities must rely on the Internet of things (IoT) technology.Therefore,combining the blockchain and IoT technology to solve the pain points of vertical industries is the current research hotspot.On the other hand,the development of IoT itself is also limited by the centralized architecture,and how to use the blockchain technology to solve the predicament of IoT is also an important issue.Although there are many blockchain related applications,some of them are actually not suitable for blockchain technology.Firstly,the proper logic of blockchain applications was discussed.Then suitable application scenarios of blockchain technology were introduced by typical case analysis.Finally,four common problems when combining blockchain and IoT were discussed.…”

Impact of overload factor on uplink SCMA system by Hongyang ZHANG, Changliang ZHENG, Yu LU, Huaping LIU

“…Sparse code multiple access (SCMA) is regarded as a promising multiple access technology for 5G because of its excellent performance.One of the major challenges that 5G networks are facing is the massive connectivity in terms of both data volume and the number of devices,thus SCMA must be capable of coping with transmission overload.Analyzing the performance of the uplink SCMA system in overloading scenarios was focused on.At first,the influence of the overloading factor on the detection and decoding complexities and error performances of the uplink SCMA system were analyzed.Then,by establishing the relationship between the overloading factor and the average sum-rate,the impact of the overloading factor on the transmission rate of the uplink SCMA system was analyzed.Extensive numerical results are provided to verify the accuracy and insights derivable from the analytical results.…”
