A wavelet transform-based ECG compression method guaranteeing desired signal quality.
This paper presents a new electrocardiogram (ECG) compression method based or orthonormal wavelet transform and an adaptive quantization strategy, by which a predetermined percent root mean square difference (PRD) can be guaranteed with high compression ratio and low implementation complexity.
