【摘要】 将载波通信技术应用于舰船照明电网电力线信道有许多困难,其复杂的噪声特性是对通信可靠性的最大挑战,因此准确的分析建模对于设计优化舰船电力载波通信系统有重要意义。本文在对所采集的电网噪声进行时频域分析的基础上,利用ARMA模型建立了两类噪声的预测模型,预测噪声较全面的反映了噪声的时频域特性。更多还原

【Abstract】 The complicated noise is main factor that influences the quality of power line carrier communication in shipboard lighting network. Therefore, accurate analysis and modeling of noise can contribute a lot in optimizing power line carrier system in shipboard lighting network. This paper builds prediction models of two kinds of noises on the basis of actual sampling noise analysis in both time and frequency domain, and the prediction noise achieves good fitness with the actual sampling noise.更多还原
