应用于电力线之杂讯滤除方法;A METHOD OF FILTERING NOISE WHICH IS APPLIED TO POWER LINE

摘要

一种应用于电力线之杂讯滤除方法，其依据信噪比产生第一高斯杂讯，并将第一高斯杂讯加于第一与一第二波形以产生第一与第二干扰波形；对第一与第二干扰波形进行多重分解重建分析以产生第一与第二重建信号波形；依据第一重建信号波形与第一波形，计算出包含最佳重建阶数资料之第一对照表，并依据第二重建信号波形与第二波形计算出第二对照表；对包含第二高斯杂讯之第三波形进行多重分解重建分析，以找出第二对照表所对应之信噪比；依据信噪比与第一对照表找出最佳重建阶数资料，藉以滤除信号波形之杂讯，以有效滤除杂讯而增加传输效果。; processing a multiple decomposition reconstruction analysis to the first and the second interference wave to generate a plurality of a first and a second reconstruction wave; calculating a first look-up table including an optimal reconstruction order information according to the first reconstruction wave and the first wave and calculating a second look-up table including according to the second reconstruction wave and the second wave; processing the multiple decomposition reconstruction analysis to a third wave including a second gauss noise to operate the SNR; finding out the optimal reconstruction order information according to the SNR and the first look-up table to filter a noise of a signal wave.
