Comparison & Performance Evaluation of Several Types of ECG Compression Techniques

ECG compression cut down on the amount of space needed to develop a telecardiology system for cardiac diagnosis and analysis. In this paper, ECG signal compression is based on different compression techniques, such as Discrete Cosine Transform (DCT), DCT2, and DCT3, Fast Fourier Transform (FFT), Fast Fourier Transform (FFT2), Discrete Cosine Transform (DCT), Chirp Z Transform (CZT), and Complex Cepstral Analysis. After the ECG signal has been compressed, each method is compared one by one. From the MIT-BIH arrhythmia database, different ECG signals are used to test these techniques. In terms of CR, PRD, QS, and SNR, the experimental results show that FFT signal compression is better.
