Data compression by discrete wavelet transform using matched wavelet

International Journal of Signal and Imaging Systems Engineering (IJSISE), Vol. 8, No. 4, 2015

Abstract: In this paper, the performance of the discrete wavelet transform is improved using matched wavelet as the mother wavelet for compression of power quality events. The matched wavelet is designed based on the characteristic of power quality event. The concept of Fractional Brownian Motion (FB-m) has been used to design the matched wavelet. The results are simulated using MATLAB version 7.3 and are compared with the mostly used Daubechies wavelet.
