Wavelet Optimization on the Lifting Scheme and Gyro Signal Denoising
Peng Jin-tao · Measurement & Control Technology · 2010
In a variety of wavelet applications,there has been a problem of how to choose an appropriate wavelet.A new method to optimize wavelet is presented,which based on the lifting scheme and the genetic algorithm.The parameters of the old wavelet according to the different objectives of signal processing are modified.With this method,an optimized wavelet corresponding to the denoising of gyroscope signal is got,and a simulation experiment is conducted.The result shows that the optimized wavelet has a better performance,besides,the wavelet optimization method is more flexible than traditional ones,and is suitable for different requirements.
