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.<<ETX>>
