英文摘要：
Wavelet transform is widely used in signal denoising, how to choice the best wavelet base according to the characteristics of the signal is one of the most important things. Aiming at the drawbacks o{ existing wavelets, a method of energy matching wavelet is proposed. According to the largest projection principle of signal in the scale space, combined with genetic optimization algo- rithm, a signal matching wavelet is constructed. In this paper, it describes the process of matching wavelet of the fluorescent signal, and also it gives the matching wavelet result. The simulation re- sults show that the matched wavelet is able to improve the performance of signal denoising com- pared with other wavelets.
