摘要
文章介绍了基于互相关的正弦信号参数特征提取方法，该方法用于从受污染信号中提取特定频率正弦信号的幅值和相位信息。文中给出了算法的详细原理和该算法噪声影响抑制能力的详细分析及仿真结果。
A algorithm, based on cross correlation, used to calculate the amplitude and phrase of polluted sine signal was introduced. In this paper, the details of this algorithm was presented, together with detailed analysis of it and the simulation results.
