摘要
提出了一种电力线通信(PLC)-可见光通信(VLC)融合的多输入多输出(MIMO)系统.采用二进制相移键控(BPSK)调制技术输入信号,依次通过PLC信道和VLC信道传输信息.仿真结果表明:相比于PLC的第二种参考信道,第一种参考信道的性能更好,且在无脉冲噪声的情况下,系统的误码率较低.此外,还研究了脉冲噪声参数对系统性能的影响.
It proposed a multiple input multiple output(MIMO) system which combined power line communication(PLC) and visible light communication(VLC).The system adopted the binary phase shift keying(BPSK) modulation technology to input the signal and transmitted the information through the PLC channel and VLC channel in turn.The simulated results showed that the performance of the first reference channel was better than the second reference channel of the PLC.What′s more,the bit error rate of the system is much lower without impulse noise.In addition,the impulse noise parameter impact on the system performance was obtained.
