提出了一种在可见光OFDM通信中的自适应方法。描述了自适应可见光OFDM系统的设计原理,介绍了系统的自适应方法,并依次对可见光OFDM系统中子载波数目的自适应性能、系统的调制方式和子载波数目相结合的自适应性能进行了仿真分析。
An adaptive method in visible light OFDM communication is proposed. The design principle of adaptive visible-light OFDM system is introduced, and the adaptive method of the system is introduced. Then the adaptive performance of the number of sub-carriers, the modulation method of the system and the number of subcarriers in the visible OFDM system are simulated in turn analysis.
