自适应OFDM系统能根据信道估计得到信道的状态信息，自适应地调节发送端传输参数，从而提高系统的性能。其中OFDM是一种多载波调制技术，具有频谱利用率高、抗多径干扰、抗突发噪声差错等优点。 在VLC中引入自适应OFDM技术，可以提升系统的容量，提高传输质量，使系统具有更大灵活性，改善系统性能。在无线光通信领域对该技术的研究已成为个重要的方向。根据现有的研究人员所发表的文献，大多是基于基础性和理论性的研究，对可见光通信技术与自适应OFDM的研究甚少。(The adaptive OFDM system can obtain the channel state information according to the channel estimation, and adaptively adjust the transmission parameters of the transmitter, so as to improve the system performance. Among them, OFDM is a multi carrier modulation technology, which has the advantages of high spectrum utilization, anti multipath interference, anti burst noise, error and so on. The introduction of adaptive OFDM technology in VLC, can improve the system capacity, improve the quality of transmission, the system has more flexibility, improve the performance of the system. In the field of wireless optical communication, the research of this technology has become an important direction. According to the literature published by existing researchers, most of them are based on basic and theoretical research, and few studies have been done on visible light communication technology and adaptive OFDM.)

或许大家都设计过数据库,也为表定义过主键,今天我想阐述的是,应该如何正确的设计一个主键,在以往的一些资料中,都没有提及到主键设计的原则.我为此总结了一下: -you might have designed the database, as well as table-defined primary key, and today I would like to explain is that How should correct the design of a primary key, in the past some of the information. no mention of the primary key design principle. I summarize this for a moment :
