| Abstract: | Spectral correlation is an efficient tool for the cyclostationary signals.Real spectral correlation characteristic can be obtained by analyzing signals under noise environments.In this paper,an improved method based on sampling interval to obtain the value is used to analyze the capability of spectral correlation for restraining noise.Simulations show the best anti-noise performance of this algorithm applied in this paper. |
