16708 通过蒙特卡洛仿真证明了该方法在信噪比为3 dB以上时，HFM信号的参数估计结果的均方误差更逼近Cramer-Rao下界，且运算量约是原来的1/3，在保证估计精度的同时提高算法收敛速度。 Finally, MonteCarlo simulation results show that, compared to the method before the improvement, the mean square error ofthe parameter estimation result of the HFM signal is closer to the Cramer-Rao lower bound when the signal-to-noise ratio is more the 3 dB, and the amount of calculation is about one-third of the method beforeimprovement, which improves the algorithm convergence speed while ensuring the estimation accuracy.
