Nonzero bandwidth performance and time delay matching of interference cancellation system by Yun-hao JIANG, Wei-feng CHEN, Shui-ming ZHONG, Hong-yun JIA, Yong-juan CAO, Peng MAO

“…The frequency-domain and time-domain characteristics of adaptive interference cancellation system were ana-lyzed,when interference signal had nonzero bandwidth.The nonzero bandwidth interference signal made the system a time-variation system.When the bandwidth was far less than the center frequency,the interference cancellation system could be approximated as an adaptive comb filter.The average convergence speed of the system was proportional to the overall reference signal gain,and the interference cancellation ratio (ICR) decreased with the increase of the bandwidth.The theoretical and simulation analyses of couple time delay matching reveal that the precise time delay matching can improve ICR significantly.…”

Secure and efficient token based roaming authentication scheme for space-earth integration network by Kaiping XUE, Yongjin MA, Jia’nan HONG, Jie XU, Qingyou YANG

“…Aiming at the problem of prolongation and instability of satellite and terrestrial physical communication links in the space-earth integration network,a two-way token based roaming authentication scheme was proposed.The scheme used the characteristics of the computing capability of the satellite nodes in the network to advance the user authentication process from the network control center (NCC) to the access satellite.The satellite directly verified the token issued by the NCC to verify the user's identity.At the same time,the token mechanism based on the one-way accumulator achieved the user's dynamic join,lightweight user self-service customization and billing,and the introduction of Bloom Filter enabled effective user revocation and malicious access management.Compared with the existing scheme,the scheme can guarantee the security of roaming authentication and significantly reduce the calculation and communication overhead of the authentication and key negotiation process.…”
