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/2-BPSK及/2-QPSK调制的影响较小，而对/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/2-QPSK调制，在硬件减损很小时可采用/2-16QAM调制。Abstract: 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.
