Research for Parameter Estimation of Linear Frequency Modulation Signals
Hai Sheng Liu, Chen Cang · Applied Mechanics and Materials · 2014
In order to conduct estimation of parameters in signal processing, using maximum likelihood estimate and the minimum mean square error estimate and maximum a posteriori probability in Bayes estimate . The experimental results show that: the maximum likelihood estimate accuracy, but search volume greatly; and Bias estimation to a certain extent, can improve the operation speed, but lower precision. So in the actual operation, select appropriate estimate methods based on the specific conditions.
