Abstract

In view of the low steady-state accuracy of the traditional adaptive filtering algorithm for the estimation of sparse system parameters under non-zero mean non-Gaussian noise interference environment, this paper designed a novel sparse adaptive filtering algorithm by using the correntropy with variable-center as the cost function and employing the proportional update mechanism. The center of the correntropy with variable center could be located at any position, which could well match the error distribution of non-zero mean, and the proportional update mechanism gave variable step parameters for each weight parameter, and thus enhancing the tracking ability of the algorithm. This method further used an online learning method to estimate the kernel width and center adaptively to improve the performance of the algorithm. In addition, this paper studied the convergence of the algorithm according to the energy conservation relation. The simulation results show that the proposed algorithm is superior and robust to the estimation of sparse parameters in non-zero mean non-Gaussian noise environment compared with traditional adaptive filtering algorithms.
