摘要: Most of the recent electrocardiogram (ECG) compression approaches developed with wavelet transform are implemented using discrete transform. Conversely, packets (WP) not extensively used, although they an adaptive decomposition for representing signals. In this paper, we present a thresholding-based method to encode ECG signals WP. The design compressor has been carried out according two main goals: 1) scheme should be simple allow real-time implementation; 2) quality, i.e., reconstructed signal as similar possible original signal. proposed is versatile far neither QRS detection nor priori information required. As such, it can thus applied any ECG. Results show that WP perform efficiently and now considered alternative in applications
