    Interference mitigation for satellite-terrestrial heterogeneous coexistence cognitive MIMO system based on DBF by Yong LIAO, Tao WANG, Huan CHEN, Xin ZHOU, Yu-feng LI

    Published 2014-10-01
    “…For the coexistence and increasing interference of satellite-terrestrial network and terrestrial wireless network,a typical scenario where the geostationary earth orbit (GEO) satellite-terrestrial network and the 4G mobile communication network coexist heterogeneously was analyzed.Besides,a multi-user cognitive system model that secondary satellite terminals interfere the primary multiple input multiple output (MIMO) 4G based stations was also proposed,with whose general signal processing was deduced.Meanwhile,digital beam forming (DBF) technology in 4G based station system was adopted to minimize the cognitive interference caused by multi-antennas and multi-users.And an optimal beam weight based on fixed azimuth interference (OBW-FAI) was proposed.Weight vector was only related to the azimuth of the interferences,thus the proposed algorithm does not need real-time and repeat calculations,and had small complexity.Finally,the numerical simulation results verify that the proposed system and algorithm can effectively reduce interference between satellite-terrestrial network and terrestrial wireless network to a certain extent.…”

    Image encryption algorithm based on multi-direction pixel continuous folding mechanism and Radon transform by Li SUN, Zhengqian HUANG, Zhenmao XIANG

    Published 2017-09-01
    “…The image encryption algorithm based on multi-direction pixel continuous folding mechanism and Radon transform was proposed.Firstly,the initial plaintext was equally segmented to get left and right sub-blocks.Then the Radon transform was used to obtain the radon projection spectrum image by processing the left and right blocks at 0~180 degrees.And Radon projection spectrum image of left block was permutated by Arnold map,while the Radon projection spectrum image of right block was permutated based on gravity model to get two su-scrambling ciphers,then the entire scrambled image is formed by combining them.To diffuse pixels from multiple directions in space,four direction continuous folding mechanism was designed to change the pixel values by using the diffusion function corresponding to four different directions for realizing image encryption.The experimental results show that this algorithm has higher security and attack resistance with more uniform of pixel distribution in output cipher compared with the current image encryption technology.…”
