Abstract

The invention discloses a bit plane noise reduction method and system based on singular spectrum analysis and a storage medium, and relates to the technical field of signal processing, and the method comprises the steps: carrying out the singular spectrum analysis of an original signal, obtaining a signal component, and reconstructing the signal component; carrying out noise degree evaluation on the reconstructed signal; converting the reconstructed signal into a bit plane matrix; calculating a bit occupied by noise, and carrying out local amplitude noise reduction; and reducing each bit vector to a decimal representation to obtain a quantized signal, and performing smoothing processing on the quantized signal to remove a quantization error to obtain a final noise reduction signal. According to the invention, through adaptive noise reduction, the problems of noise residual of reconstructed signals, distortion of original signals and the like in a traditional singular spectrum noise reduction method are solved, and the efficiency of signal noise reduction is improved.

Description

technical field [0001] The present invention relates to the technical field of signal processing, and more specifically, to a bit plane noise reduction method, system and storage medium based on singular spectrum analysis. Background technique [0002] Noise reduction is critical during signal analysis. In the process of signal acquisition and transmission, due to the interference of the external environment and the influence of its own equipment, it is inevitable that there will be noise mixed in it, and the noise will affect the target signal detection, feature extraction and regression prediction, especially in some high-precision data. In the analysis, even a very slight noise will have a huge impact on the analysis results. [0003] In reality, the noise frequency bandwidth is often unknown, and the composition is complex, so it is impossible to solve the noise reduction of all signals through specific parameters. Traditional adaptive noise reduction includes adaptive...
