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 predictive coding is used improving scalar quantizers performance. Due to the non-stationary nature of ECG signal, adaptive predictors and quantizers are more suitable than fixed configurations. Best results are obtained with an adaptive-predictive adaptive uniform quantizer for on line operation mode.
