摘　　要：提出了基于多项式-厄米多项式变换(PHPT)的多项式相位信号(PPS)参数估计算法.其基本思路是将相位系数转化为泰勒系数的估计,并用PHPT实现泰勒系数的估计.该方法为线性算法,对最低阶系数有很好估计效果,且计算复杂度比已有算法低,等效于三次FFT运算.仿真验证了该方法的有效性.A PHPT-based algorithm is proposed for parameter estimation of high-order polynomial phase signal（PPS）.The basic idea is to translate the phase parameters estimation into the estimation of the corresponding Taylor coefficients of the signal,and Taylor coefficients are estimated by using PHPT.As a linear algorithm,the proposed method has a good performance for the estimation of the lowest-order phase coefficient,and the computational complex is about three FFT operations,which is lower than the exist ones when the phase order is more than three.Computational simulations are presented to illustrate the effectiveness of the proposed algorithm.
