摘要

通过分析电力线信道传输特性，建立相应的数学模型，研究了电力线信道的多径特性，并结合一种新颖的压缩感知处理技术，提出了一种基于压缩感知的电力线信道估计方法。通过分析研究电力线信道传输特征，利用其稀疏性，只需采集、提取、存储少量的噪声与信道特征有效参数，大大降低了数字信号处理模块的数据处理量，降低了对存储硬件的要求与硬件成本。

Abstract

Through the analysis of power line channel characteristics

the corresponding mathematical model was established

the multipath channel characteristics of power line were studied.Combined with a novel compressed sensing and processing technology

a channel estimation method of power line based on compressed sensing was proposed.The transmission characteristics of power line channel were analyzed.Taking advantage of its sparse

only a small amount of noise and channel parameters needed to be collected

extracted and stored

which greatly reduced the digital signal processing module of data processing

and the storage hardware requirements and hardware costs were reduced.
