围绕60 GHz载波频率的多个GHz国际可用免许可频谱具有适应高吞吐量无线通信的能力。虽然这种自由频谱的大小和可用性使其对无线应用非常有吸引力，但60 GHz的实现必须克服许多挑战。例如，60ghz无线信道的高衰减和定向特性以及60ghz收发器中的有限增益放大器和过多的相位噪声都是明确的实现困难。与该信道相关的挑战促使短距离无线局域网、无线个人区域网络和车载网络的商业部署。本文详细介绍了60ghz物理层算法的设计权衡，包括调制、均衡和时空处理。通过考虑电路设计的局限性、有效无线信道（包括天线）的特性以及支持当前和下一代60 GHz无线通信应用的性能要求，加强了讨论。
Multiple GHz of internationally available, unlicensed spectrum surrounding the 60 GHz carrier frequency has the ability to accommodate high-throughput wireless communications. While the size and availability of this free spectrum make it very attractive for wireless applications, 60 GHz implementations must overcome many challenges. For example, the high attenuation and directional nature of the 60 GHz wireless channel as well as limited gain amplifiers and excessive phase noise in 60 GHz transceivers are explicit implementation difficulties. The challenges associated with this channel motivate commercial deployment of short-range wireless local area networks, wireless personal area networks, and vehicular networks. In this paper we detail design tradeoffs for algorithms in the 60 GHz physical layer including modulation, equalization, and space-time processing. The discussion is enhanced by considering the limitations in circuit design, characteristics of the effective wireless channel (including antennas), and performance requirements to support current and next generation 60 GHz wireless communication applications.
