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 background, the calculation of Optical Communication Ook (On-Off Keying) modulation error rate of the Matlab code, beginners can be used to understand the optical communication modulation process, and applied to their own future in-depth study, the key technology, program modulation is Binary On-Off Keying (Ook: On-Off Keying) , also known as binary amplitude Keying (2ASK) , it is a unipolar non-return-to-zero sequence to control the sine wave carrier on and off. Because Ook's anti-noise performance is not as good as other modulation methods, so this modulation method is not used in the current satellite communications, digital microwave communications, but because this modulation method is simple to realize, in the Fiber-optic communication system, amplitude keying (am) has been widely used. The analysis method of this modulation is basic, so the basic theory of digital modulation can be studied from the OOK .
