【Abstract】 Wavelet packet transformation is the further development of wavelet transformation and it can offer better resolution than that of wavelet transformation. The choice of wavelet base function directly affects the wavelet packet transformation processing result to signal. Power line’s noise is an important factor which affects PLC. This paper gives a PLC wavelet packet noise cancelling method by using multiwavelet functions. Its feasibility is proved by processing actual signals.更多还原
