In this paper, a deconvolution approach based on time frequency representation (TFR) methods is used for the estimation and analysis of biomedical signals. Chosen as examples are electroencephalogram (EEG) as well as the Electrocardiogram (ECG) signals for normal and abnormal patients. In particular, an iterative procedure is applied to calculate the required time-frequency distributions for the different types of cases under study. The deconvolution method can be defined as the process of recovering the input to some system from its output given information about that particular system. This kind of procedure is used in the field of time-frequency analysis for enhancing the resolutions of the signals under testing. These advantages are used in this paper for the biomedical applications area.
Keywords: Sleep scoring, electroencephalogram, electrocardiogram, deconvolution.
