| 摘 要： | 为了提高白光LED可见光通信系统的性能，实现有限带宽的高效利用，目前广泛采用具有较高的正交频分复用技术，在实际中易对设备和人眼造成伤害，本文介绍了一种具有较低峰值平均功率比的单载波频分多址技术。并模拟室内通信信道进行仿真，结果表明在相同信噪比情况下单载波频分多址技术具有更低的峰值平均功率比和误码率。

| Abstract: | To improve the performance of VLC system and realize the high-efficiency of its limited frequency band, the technology of OFDM was widely adopted, but it has higher PAPR which is harm to device and human eyes. In this paper, the technology of Single-Carrier FDMA is introduced. And the simulation result with indoor communication channel indicates that the BER and PAPR of Single Carrier FDMA system is lower than OFDM under the same SNR. |
