WebNov 21, 2024 · The filters used for comparison include the EKF, DD1, HDD1, UKF, DD2, and HDD2. The results show that with a very large kernel bandwidth, the performances of the CDD1 and CDD2 filters are similar to those of standard DD1 and DD2 filters; with a proper kernel bandwidth, the CDD2 filter exhibits the best performance for the non … The Gaussian filter is non-causal which means the filter window is symmetric about the origin in the time-domain. This makes the Gaussian filter physically unrealizable. This is usually of no consequence for applications where the filter bandwidth is much larger than the signal.
