Scalar quantizers for compression of ECG signal with orthogonal transforms

Abstract:

In this work we analyze several scalar quantizers applied to transform coding of ECG signal. In order to reduce the variance of the transform coefficient series pbkp_redictive coding is used improving scalar quantizers performance. Due to the non-stationary nature of ECG signal, adaptive pbkp_redictors and quantizers are more suitable than fixed configurations. Best results are obtained with an adaptive-pbkp_redictive adaptive uniform quantizer for on line operation mode.
