Abstract :
After analyzing the inherent shortcomings of the canonical wavelet transform algorithm, an algorithm to improve the coefficient accuracy is presented based on the complementary of the orthogonal wavelet filter. A typical simulation signal is used to verify the validity of the algorithm. The test results indicate that the improved wavelet algorithm is effective in overcoming the deficiencies of the canonical method.
