ECG Compression Technique Using ASCII Character Encoding and Transmission Using GSM Transmitter

Software based new, efficient and reliable ECG data compression and transmission scheme is proposed here. It is observed that this proposed algorithm can reduce the file size significantly (CR=15.72) without altering the significant clinical information (PRD=7.89%). The compression scheme is such that the compressed file contains only ASCII characters. These characters are transmitted using Global System for Mobile Communication (GSM) based Short Message Service (SMS) system and at the receiving end original ECG signal is brought back using just the reverse logic of compression. The compression and reconstruction algorithms are implemented on C-platform and SMS generation and collection algorithms are implemented on MATLAB 7.1 environment.
