Compression of the Highly Correlated Measurement Signals using DPCM Technique
Keywords:ECG signal compression, DPCM system, linear prediction, logarithmic µ-law quantizer
AbstractCompression of highly correlated measurement signals is considered using DPCM/ADPCM (Difference Pulse Code Modulation/Adaptive Difference Pulse Code Modulation) technique. It is important since very often transmission and storage of measurement signals are needed. Theory is applied on ECG (Electrocardiogram) signal, as an example of highly correlated signals. Very good performances are achieved: high compression rate and high improvement of performances are obtained.
