说明：  该程序包含ASK的发送和接收子程序，发送直接运行即可，将读入一个输入的字符串，然后进行ASK调制，发送序列还包含两段重复的ZC序列，以便接收机进行帧同步；接收机首先进行帧同步找到数据帧的起始位置，然后进行2ASK的解调。程序支持任意长度的字符串解调。帧结构包含12bit的长度指示信息。经SDR平台验证，效果良好。
(The program includes the sending and receiving subroutines of ASK, sending direct operation, reading into an input string, and modulating the ASK. The transmission sequence also contains two repeated ZC sequences so that the receiver performs frame synchronization; the receiver first performs frame synchronization to find the starting position of the number of frames and then performs 2ASK Demodulation. The program supports string demodulation of any length. The frame structure contains the length indication information of the 12bit. Verified by SDR platform, the effect is good.)
