摘要： A method and system for a single chip integrated Bluetooth and FM transceiver and baseband processor are provided. The single chip may comprise a Bluetooth radio, an FM radio, a processor system, and a peripheral transport unit (PTU). FM data may be received and/or transmitted via the FM radio and Bluetooth data may be received and/or transmitted via the Bluetooth radio. The FM radio may receive radio data system (RDS) data. The PTU may support digital and analog interfaces. A processor in the processor system may time-multiplex processing of FM data and processing of Bluetooth data. The single chip may operate in an FM-only, a Bluetooth-only, and an FM-Bluetooth mode. The single chip may reduce power consumption by disabling portions of the Bluetooth radio during FM-only mode and/or disabling analog circuitry when performing digital processing. Communication between Bluetooth and FM channels may be enabled via the single chip.

摘要： Methods and systems for processing signals are provided and may include removing a DC component from a signal envelope comprising a combined signal within a range of allocated FM channels to generate a modified signal envelope. Fluctuation in power in the signal envelope may be detected based on a ratio of a magnitude of the signal envelope and a magnitude of the modified signal envelope. The removing may further include low-pass filtering the signal envelope to generate a low-pass filtered signal envelope. A square values of the low-pass filtered signal envelope may be determined to generate a squared signal envelope. The squared signal envelope may be high-pass filtered to generate a high-pass filtered signal envelope. The fluctuation in power in the signal envelope may be detected based on a ratio of a magnitude of the high-pass filtered signal envelope and a magnitude of the low-pass filtered signal envelope.

摘要： Certain aspects of determining a signal quality metric in event of a CRC false positive may comprise measuring an amplitude and/or phase of at least a portion of a phase shift keyed section of a frame. The measured amplitude and/or phase may be checked to determine if it lies within a range of a reference amplitude and/or phase respectively. An amplitude and/or phase counter may be incremented if the measured amplitude and/or phase lies outside the range of the reference amplitude and/or phase respectively. A confidence level value of a cyclic redundancy check (CRC) for at least a portion of the phase shift keyed section of the frame may be determined based on a determined value of the incremented amplitude and/or phase counter.
