Abstract :
The improved zero tree wavelet coding algorithm is presented in the paper. This algorithm is highly effective and simple for signal compression processing. The wavelet transformation compression algorithm based on the technique is performed for an electrocardiogram signal (ECG) using the MATLAB language. The results are superior to the traditional algorithm used in ECG compression
