摘要

提出了一项研究结果，探讨了利用叠置正交变换(LOT)对心电图数据进行压缩的可行性。与传统的离散余弦变换相比，重构信号中的块效应得到了降低，而比特率和性能保持不变。介绍了一种适用于VLSI体系结构的LOT快速计算算法。

Electrocardiogram compression using lapped orthogonal transform

The results of a study to examine the feasibility of electrocardiogram (ECG) data compression using the lapped orthogonal transform (LOT) are presented. The blocking effects in the reconstructed signal are shown to be reduced, while the bit rate and the performance of the proposed scheme remain the same, as compared with the traditional discrete cosine transform. A fast computing algorithm of the LOT adaptable for VLSI architectures is described.<>
