| 摘 要： | 运用Labview软件实现了多声源分离的仿真实验,该实验以基于负熵的快速ICA算法为理论基础。在此基础上模拟了两个独立的源信号,它们经过混合后形成了两个混合信号,通过模拟实验验证了混合信号的准确分离。该结果为以后实现噪声源的定位及可视化奠定了基础,在机器故障的监测等方面有非常重要的应用价值。

| Abstract: | Simulation experiment for multiple sound source separation,which is based on fast ICA algorithm of negentropy as the theoretical basis ,is realized by using Labview software in this paper. On the foundation of the algorithm and Lahview software, two kinds of independent source signal are simulated respectively. After mixed, two kinds of hybrid signal are formed, accurate separation of which is confirmed by simulation experiment. The result establishes the foundation of realizing sound source localization afterward, and possesses quite important application value on some aspects such as monitoring ma- chine fault. |
