Index modulation aided frequency hopping anti-jamming and encryption method based on rotation scrambling by Xinjin LU, Jing LEI, Yuxin SHI

“…In order to improve the anti-jamming ability and security of the wireless communication system， an index frequency-hopping anti-interference encryption method based on rotation scrambling was designed， which could be simply called encrypted index modulation frequency hopping spread spectrum （EIM-FHSS）.Firstly， the wireless secret key was used to control multiple orthogonal frequency hopping patterns to determine the available frequencies at the current moment.The index of the active frequency （the frequency point with the modulation symbol） was used to transmit the bit information.Secondly， the secret key was used to employ scrambling encryption on the mapping table between information bits and the indexes， to ensure the security of the index bits.Finally， constellation rotation encryption was used on the symbols transmitted on the active frequency in the scheme， which ensured the security of symbol bits.Theoretical analysis and simulation results show that the proposed EIM-FHSS method has stronger security and anti-jamming abilities than the traditional IM-FHSS methods.…”

Human in vivo talocrural contributions to ankle joint complex kinematics during walking, running, and hopping by Anja-Verena Behling, Lauren Welte, Michael J. Rainbow, Luke Kelly

“…Rotation of the calcaneus about the tibia dominated frontal and transverse plane motion during hopping. Although surprisingly large ranges of talus motion were also observed in these planes (>5deg), indicating notable inter-subject variability and that the talocrural joint is not a simple hinge joint.The study highlights the importance of directly quantifying talus motion to understand ankle joint complex function. …”

On the Error Rate Analysis of Dual-Hop Amplify-and-Forward Relaying in Generalized-K Fading Channels by George P. Efthymoglou, Nikolaos Bissias, Valentine A. Aalo

“…For this system, it is hard to obtain a closed-form expression for the moment generating function (MGF) of the end-to-end signal-to-noise ratio (SNR) at the destination, even for the case of a single dual-hop relay link. Therefore, we employ two different upper bound approximations for the output SNR, of which one is based on the minimum SNR of the two hops for each dual-hop relay link and the other is based on the geometric mean of the SNRs of the two hops. …”
