The paper presents a denoising algorithm using which is particularly suited to ECG signals. The main stage of this algorithm consists in a MAP filtering in wavelet domain. Its effectiveness relies on the diversity enhancement ...

The property of shift-invariance associated with the property of good directional selectivity are important for the application of a wavelet transform in many fields of image processing. Unfortunately, the classical discrete ...

This paper represents an investigation of the wavelet based multi-carrier modulation performance in flat fading channels. The fading envelope is distributed according to a Rayleigh probability density function. BER ...
