- Improved Weighted Covariance-based Detector for Spectrum Sensing in Rayleigh Fading Channel
- IEEE WIRELESS COMMUNICATIONS LETTERSLai, Huadong Liu, Mingxing Xu, Jinqiang Luo, Peng Chen, Changrun Xu, Weichao 出版年:2024
- In this letter, we propose an improved weighted covariance based detector (IWCD) for spatially correlated time-varying Rayleigh fading channel. The proposed method uses adaptive weights that are tailored to the dynamic n...
- GLRT-based Spectrum Sensing for Non-Circular Signals in Cognitive Radios With Multiple Antennas
- IEEE TRANSACTIONS ON VEHICULAR TECHNOLOGYLai, Huadong Liu, Mingxing Xu, Jinqiang Luo, Peng Xu, Weichao 出版年:2025
- Traditional spectrum sensing schemes devised under the presumption of circular signals may suffer from performance deterioration when non-circular (NC) signals are present. To circumvent this drawback, this paper devises...
- “数字信号处理”课程教学改革探索
- 《中国电力教育》赖华东 出版年:2024
- 本文针对“数字信号处理”课程内容概念抽象、脱离工程实际等问题,围绕课程教学手段、教学内容、教学实验和教学考核四个方面提出了一系列教学改革方案。采用电子教案、课堂板书、MATLAB软件相结合的教学手段,激发学生的学习主动性...

- 脉冲噪声下基于改良Kendall’s Tau的随机信号检测
- 《图像与信号处理》肖芷菁 赖华东 徐维超 出版年:2024
- 在双通道信号检测领域,肯德尔秩相关系数(Kendall’s Tau, KT)作为一种检测器,对含脉冲噪声的信号具有显著的鲁棒性。然而,当通道间的噪声存在相关性时,KT的检测性能仍有待提升。为此,本文提出一种改进的肯德尔秩...

- Kendall's Tau based Spectrum Sensing for Cognitive Radio in the Presence of Laplace Noise
- IEEE SIGNAL PROCESSING LETTERSHuang, Yongjian Lai, Huadong Dai, Jisheng Xu, Weichao 出版年:2024
- In the presence of non-Gaussian noise, traditional spectrum sensing techniques optimized for Gaussian noise may experience significant performance degradation. To address this challenge, this paper employs Kendall's tau ...
