Research on Methods of Channels Searching/Listening and Locking using Wireless Microphone

Using an AVR controller for Channels Searching/Listening and Locking improved the application of wireless microphone which is currently based on random RF protocol.Established the concises wireless communication protocol stack to achieve public RF to private RF conversion.Design the data frame of lightweight computing to reduce the amount of data processing and synchronization requirements to improve sound quality and reduce power consumption.As aresuclt of using integrated receiver-transmitter workflow that takes the channel searching/listening and locking as a core soft module with CodeVisionAVR,the transmitter and receiver of wireless microphone is automatically connected without the interference from devices with the same frequency.It shows from the application of the improved wireless microphoue that it is suitable to be used in teaching buildings with many classroom.
