Abstract :
Improving the method of measurement frequency based on the optimal theory when applying it to measuring the weak sinusoidal signal frequency based on the modified ADVP model. Using the genetic algorithm to search the maximum variance of system output signal, and then the frequency of weak sinusoidal signal with strong noise is measured. The simulation results demonstrate this improved method is effectiveness and efficiency.
