摘要

本文对基于ofdm的毫米波通信系统的无线电参数进行了设计。首先，提出了满足5G需求的设计原则。其次，讨论了毫米波频段的TTI长度、CP长度和子载波间距等无线电参数。详细分析了相位噪声对副载波间距的影响。结果表明，相位噪声在子载波间距设计中占主导地位。基于实测相位噪声模型，推导出典型毫米波频段(30 GHz和70 GHz)的最小子载波间隔为250 kHz和500 kHz。最后提出了一种适用于所有毫米波频段的数字命理学，该数字命理学的子载波间隔为600 kHz，每子帧(1毫秒)有512个OFDM符号，能够满足毫米波系统的设计原则。

Radio parameter design for OFDM-based millimeter-wave systems

In this paper, the radio parameters are designed for OFDM-based millimeter-wave (mmWave) communication systems. Firstly, design principles are presented to meet 5G requirements. Secondly, the radio parameters including TTI length, CP length and sub-carrier spacing for mmWave bands are discussed. In particular the impact of phase noise on subcarrier spacing is analyzed in detail. It shows that the phase noise dominates the sub-carrier spacing design. Based on the measured phase noise model, minimum sub-carrier spacing of 250 kHz and 500 kHz is inferred for typical mmWave bands (30 GHz and 70 GHz). At last a numerology with 600 kHz sub-carrier spacing and 512 OFDM symbols per subframe (1 millisecond) is proposed as a unified one for all mmWave bands, which can satisfy the design principles of mmWave systems.
