Abstract
Taking access noise of receiving terminal in power line carrier communication as a research object,a noise inter-ference circumvention design based on fractional Fourier transform waveform limitation is proposed. According to spectral charac-teristic of noise,a noise signal measurement model based on time series was constructed. Since different noise signals have various time series,the power spectrum of noise signal is calculated to acquire the power spectrum. The noise signal is judged by means of noise signal measurement model based on time series. On the basis of the characteristic of noise signal in fractional Fourier do-main,the signal is transformed into Fourier domain,in which the signal is processed with one-dimensional to filter out the inter-ference signal of non-stationary wideband and retransformed into time domain. The filter was constructed in Fourier domain. The receiving terminal signal is adjusted with the threshold value to realize the design of noise signal circumvention. The experimental results show that the method can avoid the influence of the carrier communication receiving terminal on noise signal effectively.关键词
