    Information freshness orientated wireless network design for 6G by Ke XIONG, Huimin HU, Bo AI, Yu ZHANG, Li PEI

    Published 2020-03-01
    “…The development of the Internet of things has led to the deployment and application of various real-time monitoring systems (such as intelligent driving) and status update systems (such as industrial control).For the above systems,the freshness of information is particularly important.If the destination receives outdated information,it may reduce the accuracy and reliability of the system’s decision-making and cause severe security risks.In the future 6G network,the freshness of information will become increasingly important for information update applications.In order to characterize the freshness of information effectively,the academic world has proposed the concept of age of information (AoI).Recently,AoI has quickly become a new performance index and research hotspot of wireless systems.Firstly the research history of information age was reviewed.Then,the key issues of AoI introduced in different network models (such as single-user networks,single-hop networks,and multi-user networks) were analyzed.Finally the future research trend was prospected.…”

    Physical layer security of MIMO wireless systems with adaptive modulation by Hui LI, Guangqiu LI, Yancui LUO, Huizhi LIU

    Published 2023-07-01
    “…To solve the problems of low spectral efficiency and poor performance of physical layer security (PLS) in single-input single-output (SISO) wireless systems with adaptive modulation in the presence of an active eavesdropper, multiple-input multiple-output (MIMO) wireless systems with secure adaptive modulation (SAM) were proposed.The design idea was to improve the spectral efficiency of the main channel by antenna diversity technology, which used the transmit antenna selection (TAS) at the transmitter and the maximal ratio combining (MRC) at the legitimate receiver to improve the signal-to-noise ratio.Simultaneously, the PLS of the legitimate receiver was guaranteed by limiting the bit error rate of the active eavesdropper so that it could not demodulate the confidential information from the main channel.With the joint constraints of the average transmission power and PLS, the optimal switching thresholds and the analytical expressions of spectral efficiency and the eavesdropper’s average bit error rate of the SAM-MIMO systems were derived.Numerical and simulation results show that SAM systems using TAS/MRC technology can not only improve the spectral efficiency of the main channel, but also ensure the PLS against the active eavesdropper, compared with the SAM-SISO systems.…”
