摘要
简述了独立分量的基本原理和利用FastICA算法进行信号分离的理论依据,并通过仿真试验实现了混合声发射信号的盲源分离,取得了较好的分离效果。结果表明该算法收敛速度快,并具有很好的波形保持性,是一种行之有效的信号分离新方法。
The basic principle of the independent component analysis and the theory for signal separation by the FastlCA were presented. Then, simulation experiments has been done to come true the successful application of the blind source separation in the field of composite signal. It shows that this arithmetic has fast convergence speed and be good at stability of waveform, consequently providing an effective technology for the signal separation.
