| titleOfInvention | A Parametric Wavelet Threshold Signal Denoising Method Based on Improved Artificial Bee Colony Algorithm |
| abstract | The invention discloses a parameter wavelet threshold signal denoising method based on an improved artificial bee colony algorithm. First, a signal to be denoised is obtained, and wavelet transform is performed to obtain wavelet coefficients; a new threshold value is designed on the basis of a traditional threshold function. function, prove its properties through mathematical derivation, and determine the threshold parameters to be optimized; improve the original artificial bee colony algorithm; take the mean square error between the signal to be denoised and the denoised signal as the value of the improved artificial bee colony algorithm in S3 Fitness function, the optimal threshold parameter is obtained under the condition of obtaining the minimum mean square error; the optimal threshold parameter obtained by S4 is applied to the new threshold function in S2, and the wavelet coefficients are contracted to obtain new wavelet coefficients, and then inverse Wavelet transform to get the denoised signal. The present invention can obtain smaller mean square error, higher output signal-to-noise ratio and larger noise suppression ratio. |
