应用背景 计算可见光通信OOK（On-Off Keying）调制方式的误码率的 matlab代码，初学者可用于熟悉了解可见光通信的调制过程，并运用到自己以后深入学习研究中 关键技术程序中的调制方式是二进制启闭键控（OOK：On-Off Keying），又名二进制振幅键控（2ASK），它是以单极性不归零码序列来控制正弦载波的开启与关闭。由于OOK的抗噪声性能不如其他调制方式，所以该调制方式在目前的卫星通信、数字微波通信中没有被采用，但是由于该调制方式的实现简单，在光纤通信系统中，振幅键控方式却获得广泛应用。该调制方式的分析方法是基本的，因而可从OOK调制方式入门来研究数字调制的基本理论。
English Description：
Application backgroundOn-Off OOK (Keying) modulation mode of the error rate of the matlab code, beginners can be used to understand the visible light communication modulation process, and the use of their future in-depth studyKey TechnologyIn the program, the modulation mode is binary OOK:On-Off (Keying), also known as binary amplitude shift keying (2ASK), which is controlled by the single polarity of the zero sequence to control the open and close. Because the anti noise performance of OOK is better than other modulation methods, the modulation mode is not used in the current satellite communication and digital microwave communication, but because of the realization of the modulation method, the amplitude keying is widely used in optical fiber communication system. The analysis method of this method is basic, so the basic theory of digital modulation can be studied from OOK modulation mode.
