  • 摘要: 可见光通信(VLC)由于可以弥补射频通信的不足而成为研究热点,正交频分复用(OFDM)技术因其高数据速率和抗频率选择性衰落被广泛应用在VLC中。本文从能量效率、频谱效率、误码率、计算复杂度等方面对可见光通信系统中OFDM调制技术进行研究和比较,主要包括基于离散傅立叶变换的单极性方案、改进或增强型方案和混合型方案,基于哈特莱变换的光OFDM,以及基于LED索引调制的光OFDM。文中介绍了多种光OFDM调制技术的工作原理综合对比了频谱效率等性能;研究了光OFDM系统接收机改进方案;总结了可见光OFDM系统存在的问题和未来研究方向。本文对可见光OFDM系统进行归纳和总结,为提出更加高效的单极化调制技术、进一步提高系统频谱效率及可靠性提供了参考。
