Differences of the searching results Xi in the ith iteration of four proposed optimization methods and final optimization results of the conventional exhaustive search method. Four figures compare the convergences of the optimization results for the NM algorithm, the UKF method, the GA, and the PSO algorithm in the heavisine signal, the doppler signal, the bump signal, and the block signal
