Bit plane noise reduction method and system based on singular spectrum analysis and storage medium

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
