| 摘 要： | 工频通信信号的检测通常采用小波变换的方法来实现,但此方法不能有效地抑制谐波干扰,从而导致国家建立的基于工频通信技术自动抄表系统的通信可靠性变差。基于此,本文提出了一种基于小波变换和FastICA算法相结合的方法来实现对上行信号的检测。通过MATLAB仿真证明,该方法不仅能够有效地抑制谐波的干扰,而且能够有效地提取上行工频通信信号。

| Abstract: | Wavelet transform is often used to detect power frequency communication signals,but the method can’t effectively restrain harmonic interferences which leads to bad reliability of automatic meter reading system based on PFC in domestic grid.In view of this situation,the method of combination of wavelet transform and Fast ICA is proposed in this paper to achieve the detection of inbound signals.The results simulated by MATLAB show that the method not only effectively suppresses harmonics interferences but also extracts power frequency communication signals. |
