| Abstract: | Wavelet transform in the applications of ECG signal processing has been concerned by many researchers in recent years. In this paper, a methord of 5-level 5/3 lifting discrete wavelet transform(DWT)and inverse DWT(IDWT) acommplished on FPGA is proposed. And then applied to the ECG signal compression. With the mean square error controlled within the scope ,we get a greater compression ratio, and achieved the reconstruction signal by the core we designed. |
