Distortion of Correlation Analysis Caused by Identical Frequency Interference
Correlation analysis is an important method in signal processing. However, the process and mechanics that the identical frequency interference makes the correlation analysis distorted are not well understood because the expression of correlation function itself is perfect in terms of mathematics. The work carried out an investigation deep into the essence of correlation analysis, proposed a signal model that makes the mechanics of identical frequency interference clear and the experiments for further study being possible. The experimental investigations come to a conclusion that the interference may bring considerable impacts on the distortion, and it may reach as large as 100％ or even more.
