Resraech And Implementation Of Terminal RF Test Function Of 802.11ac Protocol

Nowadays,with the rapid development of wireless local area network technology,the higher transmission quality and higher transmission rate of wireless local area network technology are required.The 802.11ac standard has become a new generation wireless local area network research hotspot due to its very high transmission rate.The emergence of new standard brings higher requirements to the test instrument.Based on the IEEE 802.11ac protocol,this paper designs and implements the protocol suitable for the terminal test instrument Generate algorithms and measurement algorithms.According to the requirements of terminal RF test instrument project,this dissertation only studies the mandatory part of protocol under single-user flow in single space.The main work is as follows:First of all,the paper elaborates the project background and realization significance and systematically summarizes the basic content of IEEE 802.llac standard protocol.Then,the paper analyzes the function of each physical layer field in detail and studys the content of measurement item given in the protocol,the measurement items of modulation class are taken as the main research objectives.Secondly,the paper focuses on the IEEE 802.11ac standard signal generation and terminal radio frequency measurement algorithm research and implementation.The measurement aspect mainly introduces the method of generating each field of standard signal and the physical layer algorithm applied to it.Then,the paper realizes the algorithm and verifies with terminal RF test instrument platform.In the aspect of measurement,the thesis mainly designs the measuring process of the terminal RF signal,and focuses on the data processing,synchronization,clock skew,channel estimation compensation and EVM measurement algorithms used in the process,and finally the paper realizes the algorithm and verifies with terminal RF test instument platform.At last,the paper summarizes the full contents and optimizes the algorithm in this topic,and other models not covered in the algorithm are prospected.
