Application of Discrete Wavelet Transform with Changing Presentation of Coefficients in Data Compression in Mobile ECG Monitoring Systems

摘要

The article studies the problem of compression of data recorded by ECG sensors of mobile heart activity monitoring systems. An ECG data compression algorithm is presented which is based on transformation of coefficients of a discrete wavelet transform implemented using a computing device with limited processing power and low power consumption. The algorithm was tested on real signals and demonstrated its effectiveness.
