A new method of estimating the frequency-known signals from the strong background noise was presented first. Then the new method was used in the demodulation of
In the conceptual stage the function design process is realized by the computer aided application. After surveying on the function specification methods and the
In this paper, the reduced-order modeling (ROM)technology and its corresponding linear theory are expanded from the linear dynamic system to the nonlinear one,
Helicopter blade running elevation measurement is an important measure target in helicopter blade dynamic balance experimentation. The elevation influences the
A method of direction of arrival (DOA) estimation of coherent sources is proposed, which is based on arbitrary plane arrays. After constructing the mathematical
