Maximum Correlated Kurtosis Deconvolution (MCKD)

Maximum Correlated Kurtosis Deconvolution (MCKD) is a signal processing method for designing filters that effectively extracts impact components from noisy backgrounds. This technique utilizes the principle of maximizing correlated kurtosis to process signals through a deconvolution process, ultimately achieving the goal of impact component extraction. In practical applications, the MCKD method can be applied across various fields such as image processing and audio processing to improve the accuracy and reliability of impact component detection. Key algorithmic features include iterative optimization of filter coefficients to maximize the correlated kurtosis metric, which enhances periodic impulse detection while suppressing random noise. The implementation typically involves calculating the correlated kurtosis of the filtered signal and using optimization algorithms (like gradient-based methods) to update filter parameters. Common functions in MCKD implementations include signal windowing, convolution operations, and kurtosis computation routines.
