摘要
MIMO技术在射频通信领域已被深入研究,使空间成为一种可以用于提高通信性能的资源。无线光通信与射频通信在调制/解调方法、信道特性诸方面有很大的差异。文中评述了国内外有关无线光MIMO技术的研究进展,对无线光MIMO的提出背景进行了详细分析,最后通过实验说明了MIMO对大气湍流的抑制效应。实验结果表明:无线光MIMO不但使空间成为一种资源,提高了无线光通信的信道容量,而且可以抑制大气湍流效应,扩大了无线光通信的应用场合。
MIMO technology has been intensively studied in RF communications, enable space as a kindof resources that can be used in improving communication performance. There are lot of differencesbetween wireless optical communication and RF communication, such as modulation/demodulation methodand channel characteristics. The research progress of wireless optical MIMO technology at domestic andabroad was reviewed, a detail analysis of the background of the wireless optical MIMO was carried out. effects of MIMO inhibits atmospheric turbulence was illustrated by the experiment at last. The resultsshow that the wireless optical MIMO not only make the space as a kind of resources that can be improvethe capacity of wireless optical communication channel, but also inhibit atmospheric turbulence effect,expanded field of wireless optical communication applications.
