- 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...
- 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 ...
