Weighted Averaging of ECG Signal Using Criterion Function Minimization

Averaging signals in time domain is one of the main methods of noise attenuation in biomedical signal processing. This paper proposes a new weighted averaging method using criterion function minimization and based on partitioning of input set in time domain, which is a generalization of an existing method. Performance of the new method is experimentally compared with the traditional averaging by using arithmetic mean and another weighted averaging method based on criterion function minimization.
