| 摘 要： | 双向工频通信系统是一种基于配电网络的通信系统。通信信号在配电网中传输时,其背景信号中必然含有大量的谐波成分,这会给通信信号的检测带来极大的困难。该文根据双向工频通信的信号特征,提出了基于独立分量分析的谐波消除方法。该方法在消除谐波干扰的同时,有用信号成分几乎不被破坏。通过Matlab对此方法进行了验证,取得了良好的效果。

| Abstract: | Two-way Frequency Automatic Communication System(TWACS) is a communication system based on power distribution networks. A lot of harmonic elements exist in background signal when TWACS transmits communication signals, which will bring great difficulity to check and measure communication signal. A new meathod using Independent Component Analysis(ICA) to eliminate harmonic interference is proposed according to signal characteristics in TWACS.The method can eliminate harmonic interference nearly without destroying useful signals. The method is testified effectively through Matlab. |
