摘要
轨道角动量(OAM)为无线光通信提供了新的信息调制维度,极大地提升了系统的信道容量和频谱利用率。目前,基于OAM的新型无线光通信体制引起了学术界的极大关注。首先介绍了通信方式,其次依次综述了大气湍流随机相位屏、大气湍流下传输特性和大气湍流效应抑制策略,最后展望了自由空间OAM无线光通信的应用前景和研究趋势。
Orbital angular momentum(OAM) provides a novel information modulation degree for wireless optical communication, which can promote the channel capacity and spectral efficiency tremendously. Currently, the OAM wireless optical communication regime has attracted the highly interest of academic community. Firstly, this paper reviews the communication approaches of OAM wireless optical communication, then investigates the random phase screen for atmospheric turbulence, transmission characteristics of OAM under atmospheric turbulence and mitigation schemes for atmospheric turbulence effects. And some application prospects and research trends for OAM wireless optical communication are discussed finally.
