Performance Analysis for Ultra-high Rate Millimeter Wave Wireless Local Area Network Communication Systems

摘要: 针对中国毫米波频段（45GHz），制定下一代IEEE 802.11aj无线局域网（Wireless Local Area Network, WLAN）协议标准通信系统的物理层结构及发射机发送方式，研究了一种新的适用于该标准的循环移位分集（Cyclic Shift Diversity, CSD）方案，该方案在不增加接收机额外复杂度的前提下能够获得较好的性能。同时，本文对通信系统在各种调制和编码方式（Modulation and Coding Scheme, MCS）下的性能进行了仿真和评估。结果表明，在将系统发射功率控制在20dB时，采用码率为1/2的16-QAM调制方式可以在保证误帧率性能的同时获得较高的吞吐率。

Abstract: IEEE 802.11aj is a standard of next generation wireless local area network（WLAN） for millimeter wave band (45GHz) of China. A structure of physical layer and a structure of transmitter are designed for communication system. This paper made a research on a new scheme of cyclic shift diversity for IEEE 802.11aj standard. The scheme can achieve good performance without additional effort at the receiver. In addition, this paper made an analysis on the performance of all modulation and coding schemes. In conclusion, in order to limit the transmitting power at 20dB，the 16-QAM modulation of rate-1/2 could achieve high throughput ensuring the PER performance at the same time. -
