摘要： A method and system sharing a Bluetooth processor for FM functions are provided. The single chip may comprise an integrated Bluetooth radio, an integrated FM radio, and processor system. A processor in the processor system may be utilized for Bluetooth and FM data processing and may time multiplex between the Bluetooth and FM data processing based on interrupt signals. The processor may operate in a low power mode based on a clock signal generated from a low power oscillator. When a Bluetooth interrupt signal is received, the processor may enable Bluetooth data processing that may be based on a Bluetooth clock signal. When an FM interrupt signal is received, the processor may enable FM data processing that may be based on an FM clock signal. When data processing is complete, the processor may return to the low power mode operation.

摘要： A method and system is provided processing channel information may include in a mobile FM radio system including an integrated FM radio transmitter and FM radio receiver, dynamically generating a list of local FM channels, ranking local FM channels in the generated list, and selecting one of the ranked local FM channels for use by the FM transmitter based on neighboring channel interference. The FM radio receiver may detect FM channels being transmitted or not being transmitted, detect a pilot signal or a channel transmission pause. A tuning frequency of the FM radio receiver may be adjusted for scanning and detecting the local FM channels based on knowledge of a location of the FM radio receiver, received signal strength indicator (RSSI), dynamically scanning for local FM channel based on received RDS/RDBS data or country code, and/or carrier error of a related FM signal.

摘要： A method and system is provided for enabling communication, where a FM radio system including an integrated FM radio transmitter and FM radio receiver may use an in-band FM or out of band transmitter to communicate a dynamically generated list with alternate local FM channels to an in-band or out of band receiver of another FM radio device with a FM radio receiver. The generated list of local FM channels may be ranked according to the least neighboring channel interference and may be selected for tuning the FM radio device. The FM radio system and the FM radio device may both scan to generate a substantially matched list of local FM channels. In response to detecting a new signal of a transmitted channel by the FM radio system, the FM radio device may tune to the same channel using an open loop, closed loop or semi-open loop method.
