对一种新的噪声成分分析系统—基于自适应噪声抵消器和偏相关分析的多源噪声成分分析系统进行了研究,并用它来分析复杂的多源叠加型噪声场的组成成分,给出各源噪声成分在多源总噪声场中所占的百分比估计。利用该系统对仿真信号和某实测多源噪声信号进行处理,获得了满意的结果。
A new noise component analysis system, a multi-source noise component analysis system based on adaptive noise canceller and partial correlation analysis, is studied and used to analyze the composition of complex multi-source superimposed noise field. Estimation of the percentage of source noise components in a multi-source total noise field. The system is used to process the simulated signal and some measured multi-source noise signal, and the satisfactory result is obtained.
