摘要
研究了多项式相位信号的参数估计问题。首先通过离散伪魏格纳-威利变换得到调频信号的瞬时频率,再利用多项式拟合法来实现对多项式相位信号参数的估计。仿真实验证实了所提出的算法的有效性。
A parameter estimation method of polynomial phase signals is studied in this paper. The instantaneous frequency is estimated by using discrete pseudo Wigner-Ville transformation(DPWVT),then the polynomial fitting algorithm is used to estimate parameters for the polynomial phase signals. Simulation test shows the efficiency of this method.
