Improved bispectral adaptive power regulation algorithm for HPLC channel monitoring
The HPLC channel of wideband power line carrier communication is easily affected by non-Gaussian white noise signal,which leads to inaccurate channel monitoring results.Therefore,a HPLC channel monitoring method with improved bispectral adaptive power regulation algorithm is proposed.The signal transmission characteristics of HPLC channel were analyzed,and the signal fading transfer function was constructed.The improved bispectral adaptive power regulation algorithm is used to output the adjusting cumulant results,and the time series Fourier transform is adjusted by autoregression to obtain the bispectral processing signal.Periodic/sleep monitoring mechanism was used to realize HPLC channel monitoring according to HPLC channel classification function.The experimental results show that the channel voltage signal fluctuation obtained by this method is consistent with the actual output time-domain waveform in normal communication environment,while the channel voltage signal fluctuation error of the maximum 20 V in some time periods in abnormal communication environment is consistent with the actual time-domain waveform in other time periods.
