摘　　要：太赫兹频段无线通信已成为后5G时代研究的重点。鉴于轨道角动量不同模式之间具有良好的正交性,可以构造无限维的Hilbert向量空间等优势,该技术已成为无线通信中突破海量设备接入瓶颈的关键。为此,文中综述了基于轨道角动量无线通信的发展现状,总结了轨道角动量在无线通信应用中面临的挑战,为万物互联时代海量接入设备实现高质量多媒体通信提供借鉴。THz Communication has become the research focus in beyond 5G.Since orbital angular momen­tum(OAM)has orthogonal patterns and can build an infinite dimension Hilbert vector space,it has be­come a key technique to break the bottleneck of massive device access.This paper reviews the develop­ment and summarizes the challenges in OAM based wireless communication,thus it provide insights for massive device access and high quality multi-media communication in the era of the Internet of Every­thing.
