LINEAR PERFORMANCE OF ECG DATA COMPRESSION AND TRANSMISSION ALGORITHM FOR TELE-MEDICINE

A real-time data compression and transmission algorithm for a periodic ECG signal is used for tele-medicine. It is used for storing and
transmission purposes without affecting the signal quality, they are capable of recording and processing long records of bio signals.
The requirements of memory in the storage device having 250Hz sampling rate, 12 bit resolution and 52 megabits of memory. For
transmission applications, highly integrated compression and decompression methods are used. The aim of bio signal compression
scheme is to minimize the storage space without losing any clinically relevant information, which can be done by means of reducing
eliminating redundancies in the signal. The algorithm is used to detect the peaks of differenced ECG data and then to perform DWT
between the current peak and the previous peak of data stream. The performance level is compared to provide the optimal level of
compression by shorter symbols of sequence identical signals by RLE. The bio signal data transmission method is used to limited
bandwidth for long distance communications.
