摘要
Abstract
Random noise and signal are independent of each other. Based on this principle, the original signal can produce two different noise signals through two different channels. Then, noise can be removed by the cross-correlation operation between the two different noise signals. After the cross-correlation treatment of the noise signal, the signal amplitude is higher than that of the noise amplitude. A fractional order calculus operation is conducted on the noise signal, the gap between the signal and noise is increased, and then the noise is removed. This method is verified through demonstration and simulation. The denoising effect of this method is better.关键词
