摘　　要：利用硬件和软件组合成真随机数，产生新的随机射频协议，同时通过射频功率控制，完成了收发双方从公共射频协议到新的随机射频协议的转换，实现了无线话筒和接收机的任意配对。项目实施表明，随机射频协议是实现无线话筒和接收机任意配对的良好方案。A true random number is combined by software and hardware, with which new random RF protocol can be produced. At the same time, through controlling of RF power, transformation of sender and receiver is completed from public RF protocol to new random RF protocol, and random matching of wireless microphone and receiver is realized. The implementation of project shows that the random RF protocol is a good method to realize random matching of wireless microphone and receiver.
