平稳信号频率提取及校正

Frequency Extracting and correcting of stationary signal

提出一种频域内平稳信号处理新方法,对输出信号进行快速傅立叶变换得到其功率谱,并利用频谱校正技术对功率谱进行修正,得到信号的频率,进而相应的待测物理量。理论分析和仿真结果都表明这种方法准确、可行。

A novel method for dealing with the stationary signal was put forward.Using FFT for the output to acquire the power spectrum of the signal,and then correct the power spectrum with the technology of spectrum correction to obtain the frequency of the signal.The results show that the method is suitable for dealing with the stationary signal.
