摘要/Abstract

摘要： G3标准OFDM(正交频分复用)多载波PLC(电力线通信)技术应用于智能电网时,必须解决恶劣电力环境下的数据同步问题。当电力信道存在电力背景噪声及随机脉冲噪声时,经典的延时相关分组检测算法对数据起点检测存在较大误差。针对电力噪声的特点,为提高检测的准确度,将微分算法应用于延迟相关算法,提出新的分组检测算法。在电力噪声模型下,通过对经典算法及新的算法进行性能评测比较,验证了新算法对恶劣环境的适应性。

Abstract: When exploiting orthogonal frequency division multiplexing technology based on G3 specification on smart grid,it’s necessary to solve the synchronization in harsh powerline environment for G3-PLC system.When there are background noise and impulsive interference in powerline channel,the classic delay-and-correlate packet detection algorithm has serious error.According to the characteristic of powerline noise,the classic packet detection algorithm is improved in order to increase the accuracy of detection.Through the evaluation of classic algorithm and new algorithm,the result shows new algorithm is more accurate than classic algorithm in the condition of powerline noise model.
