Performance Evaluation and Transmitter Optimization for AN-Aided FH Communication Against Time Misalignment

引用

china Communications 2025年第03期 86-103页

作者： Song Changqing Lin Lang Qin Lizhi Xiao Fei Zhao Hongzhi Shao Shihai National Key Laboratory of Wireless Communications University of Electronic Science and Technology of China The Laboratory of Electromagnetic Space Cognition and Intelligent Control The Thirtieth Research Institude of china Electronic science and Technology Group Corporation

To guarantee secure communication against eavesdropping and malicious attack, an artificial noise(AN)-aided frequency-hopping(FH) architecture is adopted in this article. But the inevitable time misalignment between the received signal and locally reconstructed AN will deteriorate the AN cancellation performance, yielding significant secrecy degradation at the FH receiver. In view of this, first, the AN cancellation performance under time misalignment is evaluated via signal to AN-plus-noise ratio,and the system secrecy is analyzed via secrecy ***, to mitigate the performance degradation raised by time misalignment, the transmitting power allocation scheme for AN and confidential signal(CS)is optimized, and the optimal hopping period is designed. Notably, the obtained conclusions in both the performance evaluation and transmitter optimization sections hold no matter whether the eavesdropper can realize FH synchronization or not. Simulations verify that time misalignment will raise non-negligible performance degradation. Besides, the power ratio of AN to CS should decrease as time misalignment increases,and for perfect time synchronization, the transmitting power of AN and CS should be equivalent. In addition, a longer hopping period is preferred for secrecy enhancement when time misalignment gets exacerbated.

china Communications 2025年第03期 36-53页

作者： Pan Wensheng Shi Chengzhe Li Tong Shen Ying Shao Shihai National Key Laboratory of Wireless Communications University of Electronic Science and Technology of China Laboratory of Electromagnetic Space Cognition and Intelligent Control

To enable simultaneous transmit and receive(STAR) on the same frequency in a densely deployed space with multi-interference sources, this work proposes a digitally-assisted analog selfinterference cancellation method, which can acquire reference signals through flexible wired/wireless switching access. Based on this method, the Minimum Mean Square Error algorithm with known channel state information is derived in detail, determining the upper limit of the cancellation performance, and the Adaptive Dithered Linear Search algorithm for real-time engineering cancellation is *** correctness of theoretical analysis is verified by the practical self-interference channel measured by a vector network analyzer. Furthermore, we have designed and implemented the corresponding multiinterference cancellation prototype with the digitallyassisted structure, capable of handling multiple interferences(up to three) and supporting a large receive bandwidth of 100 MHz as well as a wide frequency coverage from 30 MHz to 3000 MHz. Prototype test results demonstrate that in the presence of three interferences, when the single interference bandwidth is 0.2/2/20 MHz(corresponding to the receive bandwidth of 2/20/100 MHz), the cancellation performance can reach 46/32/22 d B or more.
