摘要
本文研究了家用电力线在50 ~ 550 MHz频段的超宽带(UWB)传输特性。对室内电力线信道在超宽带通信中的应用特性进行了测试和软件仿真。首先，在频域和时域测量宽带信道特性，然后在系统级对0 / b E - N下的误码率性能进行仿真。本文提出了一种利用MB-OFDM超宽带模型进行宽带电力线通信的概念。结果表明，利用电力线信道在50 ~ 500mhz范围内传输超宽带信号，实现了高数据速率传输。
Measurement and simulation of powerline channel using OFDM for UWB communication
This paper presents the study of the UWB (Ultra Wideband) transmission characteristics over household powerline in a very high frequency band, from 50 MHz to 550 MHz. The characteristics of indoor powerline channels are examined for its use in UWB Communication in both measurements and software simulations. Firstly, broadband channel characteristics are measured in both frequency and time domain, followed by system level simulation of BER performance versus 0 / b E N . This paper presents a concept of utilising the MB-OFDM UWB model for broadband powerline communication. Results indicate that high data rate transmission is possible, by exploiting the powerline channel for UWB signal transmission in 50 – 500 MHz.
