Abstract
An interference-resistant method for a wireless audio system capable of transforming an audio signal into an RF signal includes transforming the audio signal into a PCM signal, appending a first control signal to the PCM signal, and modulating the PCM signal with the first control signal into an analog base-band signal. The method further includes up-converting the analog base-band signal into the RF signal and transmitting the RF signal into the air in a transmitting mode and receiving the RF signal in the air during a receiving mode. The channel is switched to another one upon determining that a Received Signal Strength Indicator (RSSI) level of the RF signal is greater than a first predetermined value a plurality of times within a predetermined time interval.
