摘　　要：基于IEEE 802.11ad标准,该文设计了单载波(Single-Carrier,SC)60 GHz通信系统的物理层结构,并对系统性能进行评估。研究了硬件减损(hardware impairments)对通信性能的影响,包括相位噪声及功率放大器(Power Amplifier,PA)的非线性影响,且PA非线性的影响更为显著。结果表明,硬件减损对π/2-BPSK及π/2-QPSK调制的影响较小,而对π/2-16QAM的影响较大。为获得较高的通信速率且保证较好的通信性能,一般情况下应选择π/2-QPSK调制,在硬件减损很小时可采用π/2-16QAM调制。In order to analyze the performance of Single-Carrier（SC） 60 GHz communication system,a structure of physical layer is designed based on IEEE 802.11ad standard.The impacts of hardware impairments on the communication performance are studied,including phase noise and non-linear distortion of Power Amplifier（PA）,and the non-linear distortion is more significant.Simulation results indicate that the performance degradation caused by hardware impairments is much less for /2-BPSK and /2-QPSK modulation than that for /2-16QAM modulation.To get a high bit rate and acceptable performance,/2-QPSK modulation is a good choice in general,and /2-16QAM is better when hardware impairments are trivial.
