The application prospect of air-sea cross-border communication is broad. Magnetic induction (MI) communication can realize two-way cross-border transmission, adapt to complex marine environment and be easy to carry. Therefore, it has unique advantages in cross-border transmission. However, due to the characteristics of near field propagation in magnetic induction communication, the range × data rate performance of magnetic induction communication is severely limited, which is a difficult bottleneck problem to break through. Aiming at this problem, this paper proposes a cross-border magnetic induction relay cooperative communication scheme based on distributed space-time coding. In this scheme, relay nodes are introduced between the transmission and reception of cross-border transmission, and distributed space-time coding (DSTBC) is used on the relay nodes to coordinate the forwarding of each relay node so as to obtain the spatial diversity gain. Using the diversity gain, the underwater communication range of cross-border communication can be extended. Simulation results show that the DSTBC coding scheme can significantly improve the transmission performance of wireless channels. When the system bit error rate is 10-4, compared with the simple forwarding relay system, the code-forwarding system using 2, 3, and 4 relay nodes can obtain about 3 to 6dB of diversity gain. © 2022 IEEE.

Electromagnetic interference poses a threat to global navigation satellite systems (GNSS) used in various civilian applications. Sparse representation has been extensively studied for interference cancellation. However, dictionaries of non-stationary signals are difficult to construct due to their time-varying characteristic. Therefore, the mitigation of non-stationary interference is still a challenging issue. This paper proposes an adaptive dictionary construction approach for sparse representation of non-stationary interference. The proposed algorithm utilizes the non-stationary signal analysis tool, Wigner-Ville distribution (WVD), to provide prior knowledge. The overcomplete dictionary is constructed adaptively based on the instantaneous frequencies estimated from WVD. The proposed approach can reconstruct non-stationary interference successfully exploiting the adaptive dictionary. The simulation results confirm that the proposed interference suppression algorithm can successfully mitigate the interference and achieve GNSS signal acquisitions. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Based on quantum parallelism theory and quantum phenomena such as superposition and entanglement, quantum reinforcement learning (QRL) has the potential to surpass classical reinforcement learning (RL). Although some excellent works have been done on QRL, existing RL methods encounter chanllenges when performing in environments with sparse rewards. In this paper, we provide a new perspective on conducting temporal difference (TD) learning in quantum computing, which can eliminate redundant exploration steps compared to classical methods. Specifically, we first use environment information to construct a world model with quantum circuits, enabling it to interact in a quantum way. Then, we perform the learning process by using the quantum world model and Grover's algorithm to query backwards how to reach the recorded states with high TD-errors. Simulation results show that our proposed method has superior performance compared to classical RL algorithms. © 2024 IEEE.

The disturbance of atmospheric turbulence during laser transmission is a major problem in the field of high-energy laser transmission and communication. Fast and real time wavefront sensing is one of the key technologies in adaptive optical systems. For laser emission or communication systems with relatively smaller optical apertures and transmission distances, atmospheric aberration is mainly composed of low-order Zernike modes with weak intensity. Traditional Hartmann wavefront sensor works by regional segmentation and reconstruction of the wavefront plane, which need complicated matrix calculation, inducing considerable time delay. Its application in laser wavefront sensing can be technically sophisticated and redundant. Holographic modal wavefront sensing technology takes advantage of parallel modal detection method to obtain the intensity of specific modes of aberrations carried by the laser directly. With benefits of higher speed, smaller time delay, and compact system structure, it may be more suitable for atmospheric laser wavefront sensing. Here, we carried out simulation research on holographic modal wavefront sensor and its application in atmospheric laser wavefront sensing, the measuring accuracy and validation frontier of this technology are analyzed. The result provided informative support on high speed laser aberration sensing and correction. © 2022 SPIE

In the contemporary era of information technology, the exponential surge in data has rendered colossal potential value, which would be fully unlocked through data circulation and sharing. However, when the data contains sensitive information, special attention must be paid to the data privacy and security problem for data sharing. A feasible solution is to incorporate blockchain technology into the data sharing system, and the new challenge is how to provide fair rewards for data owners to motivate them to contribute data. To address this challenge, in this paper, we first design a blockchain-based data sharing system to enhance the trust and reliability of the data shared among participants. Then we propose an incentive allocation method based on the Shapley value, which comprehensively incorporates each participant’s contribution while ensuring fairness for the allocation. Finally, multiple numerical simulations are conducted to validate the effectiveness of the proposed mechanism. © Beijing HIWING Scientific and Technological information Institute 2024.

Unified and Complete Point Addition Formula for Elliptic Curves

引用

Chinese Journal of Electronics 2023年第2期21卷 345-349页

作者： Lijun Zhang Kunpeng Wang Hong Wang Science and Technology on Communication Security Laboratory Chengdu China State Key Laboratory of Information Security GUCAS Beijing China

As is well known, the unified point addition formula is useful for resisting side channel attacks in elliptic curve cryptography. Furthermore, if the unified formula is complete, which means it is valid for any two points, then there are no exceptional cases to be described particularly. This feature is especially preferable for elegant codes of elliptic crypto-algorithms. Therefore, the unified and also complete point addition formula can provide the advantage for good security and convenient implementation. In this paper, we exploit sufficient and necessary condition for the existence of unified and complete point addition formula on several known elliptic curve models such as Weierstrass cubics, Jacobi quartics, Edwards curves, etc.. Moreover, we study another form of elliptic curves called Selmer curves. For practical application, we finally give some numerical examples of cryptographic secure Selmer curves.
