A wavelet transform-based ECG compression method guaranteeing desired signal quality
Jie Chen,Shuichi Itoh +1 more
TL;DR: A new electrocardiogram compression method based on 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 are presented.
Journal ArticleDOI
Irregular sampling theorems for wavelet subspaces
TL;DR: An algorithm is presented which can relax the upper bound for sampling in some wavelet subspaces by using scaling functions and which can estimate a proper upper bound of sup/sub /spl kappa//|/spl delta//sub / spl kappa| such that the irregularly sampled signals can be recovered.
Journal ArticleDOI
On sampling in shift invariant spaces
TL;DR: A necessary and sufficient condition for sampling in the general framework of shift invariant spaces is derived and an improved estimate for the perturbation is derived for theperturbation of regular sampling in shift invariants spaces.

ECG Data Compression by Using Wavelet Transform
Journal ArticleDOI
A hierarchical group key management scheme for secure multicast increasing efficiency of key distribution in leave operation
TL;DR: An efficient protocol and associate algorithm for group key management in secure multicast based on a hierarchy approach in which the group is logically divided into subgroups and the inverse value of the leaving member is sent to the subgroups when a member leaves.
