    摘要: 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.

    摘要: An apparatus includes a receiving circuit, a demodulation module, a frame synchronization control module, a filter, and an audio conversion device. The receiving circuit is used to receive a radio frequency signal and generate a corresponding baseband signal. The demodulation module is electrically connected to the receiving circuit for demodulating the baseband signal and for correspondingly outputting sequential data. The frame synchronization control module is electrically connected to the demodulation module for synchronizing the data and outputs the sequential data. The filter is electrically connected to the frame synchronization control module for filtering out erroneous data outputted from the frame synchronization control module. The audio conversion device is connected to the filter for transferring an output of the filter into a corresponding audio signal.

    摘要: In a method of updating a set of candidate frequency channels during wireless communications between a radio port and a mobile communications device, the communications device switches to a current measured one of multiple pre-stored frequency channels not in a current set of candidate frequency channels to measure signal quality after an assigned time slot of a current time frame of a second time sequence, and switches back to a current working frequency channel prior to the assigned time slot of a succeeding time frame of a first time sequence. The mobile communications device updates a current set of the candidate frequency channels with the current measured frequency channel when the signal quality attributed to the current measured frequency channel is better than those attributed to the current set of the candidate frequency channels.
