面向多媒体教室的任意配对数字无线话筒设计

如何避免多媒体教室无线话筒的同频设备干扰,一直是值得研究的课题.利用非标准通信协议思想,提出一种以硬件和软件组合成真随机数,产生新的随机射频协议,避开同频设备干扰,实现无线话筒发射机与接收机的无干扰任意配对.项目实施表明,基于非标准随机射频协议的数字无线话筒,适应多媒体教室设备的发展.

Design of Random Matching Digital Wireless Microphone Oriented Multi-media Classroom

It is desirable to study on how to avoid the interference of the same frequency equipment of the wireless microphone in multi-meda classrooms all the time. Using the thought of non-standard communication protocol, a new random RF protocol is produced by the true random, which is combination of hardware and software, to avoid the interference of the same frequency equipment. As a result, no interference random matching of the transmitter and receiver in wireless microphone has been realized. The item implement shows that the digital wireless microphone based on non-standard random RF protocol, is in line with the development of multi-meda classroom equipment.
