Applying Median Filtering Algorithm to Nonlinear Frequency Estimation of MPSK Modulated Signals
中值滤波算法在MPSK信号非线性频率估计中的应用研究

Based on the nonlinear frequency algorithm, the nonlinear transform of white Gaussian noise, which is added to the received signals are analyzed. And the idea of applying median filtering algorithm to nonlinear frequency estimation is proposed. At the same time,Monte Carlo simulation is used to validate the idea. The results show that the Mean Square Error (MES) of frequency estimation using median filter is more perfect than using mean value filter.
