短时傅里叶变换常用于缓慢时变信号的频谱分析，可以观察沿时间变化的频谱信号。 其优点如下图所示，弥补了频谱分析中不能观察时间的缺点，也弥补了时域分析不能获取频率的缺点。
Abstract: This paper presents the evaluation of an image restoration approach based on a bilateral Gaussian filter (BGF) to address signal identification for spectrum sensing. The proposed methodology ...
Human inventions, namely engineered systems, have relied on fundamental discoveries in physics and mathematics, e.g., Maxwell’s equations, Quantum mechanics, Information theory, etc., thereby applying ...
In order to achieve the highly efficient and accurate identification of fracture modes including tension or shear fractures during rock failure, an intelligent identification method based on ...
