| Abstract: | In this thesis a new generalized correlation algorithm and its train of thought to be invented are described in detail and several main causes in comparison with traditional correlation analysis method in time delay estimation are analysed. The new algorithm merges the advantages of two techniques:Cepstrum and Correlation. It can detect the time delay peak that traditional method cann't distinguish from signals with strong background noise. It is shown from the experimental and theoretical results that the new method has wide application prospect. |
