摘要： 对正弦信号频率估计的几种插值算法进行了研究，重点介绍了一种精度较高的三次插值算法，针对其估计误差仍然较大，而且在频率接近某一区域时精度下降的情况，提出了一种修正算法，仿真结果证明该算法在只增加少量计算量的情况下性能非常优越。
Abstract: This paper investigates some interpolated algorithm of sinusoid signal frequency estimation，emphasizes a cubic interpolated algorithm which has high precision，meanwhile notices that the estimation error is still tool large，and the precision will be very low on some condition，so proposes an improved algorithm.The simulation result proves that the performance is excellent despite the gently larger computation.
