摘要： A method for synchronizing baseband clocks in an OFDMA wireless microphone system is disclosed. An example method includes receiving a plurality of pilot subcarriers from an audio transmitter. The method also includes determining a timing offset estimate based on the pilot subcarriers. The method further includes determining a tuning value by passing the timing offset estimate through a proportional-integral controller. The method still further includes determining a modified reference signal by modifying a reference oscillator based on the tuning value. And the method yet further includes controlling (i) an audio sample clock and (ii) an antenna data clock based on the modified reference signal.

摘要： A wireless audio system using low overhead in-band control and audio transmission is provided. The wireless audio system includes a first wireless audio device configured to operate separate physical layer channels for audio data and control data, and transmit the audio data and control data using a single wideband carrier. The wireless audio system also includes one or more second wireless audio devices configured to receive the audio data and control data, and execute an instruction based on the control data.

摘要： A wireless microphone system is disclosed. The system includes a plurality of wireless microphones each classified in accordance with one or more audio quality parameters. The system also includes a control device communicatively coupled to the plurality of wireless microphones. The control device is configured to determine that a first wireless microphone corresponds to a first audio classification, and that a second wireless microphone corresponds to a second, different, audio classification. The control device is also configured to determine a first modulation and coding scheme for the first wireless microphone based on the first audio classification, and a second modulation and coding scheme for the second wireless microphone based on the second audio classification. The control device is further configured to transmit, to the first and second wireless microphones respectively, the determined first and second modulation and coding schemes.
