摘要： Methods and systems for wireless communication are disclosed and may include controlling one or more scans of a received signal detection frequency across a frequency range and storing a magnitude of the received signal at each frequency where the magnitude exceeds a threshold level. A type of one or more signals in the received signal may be determined based on a bandwidth of the signals. A Bluetooth page/inquiry scan may be initiated if the determined type is a page/inquiry signal, and scans may be continued if the determined type may not be a page/inquiry signal. The scans may be repeated on a periodic basis and may be controlled utilizing a voltage controlled oscillator. Each of the scans may include a plurality of discrete frequency steps or a continuous frequency ramp. The controlling may include a start frequency, an end frequency and a frequency step size for the scans.

摘要： Aspects of a method and system for detecting Bluetooth signals utilizing a wideband receiver are provided. In this regard, a portion of a frequency band may be scanned multiple times, where each scan comprises receiving signals present in the scanned portion of the frequency band. Based on results of a Fast Fourier Transform performed on the received signals, presence of one or more Bluetooth transmissions in the received signals may be detected. In instances that a Bluetooth transmission is detected, a type of the Bluetooth transmission may be determined based on a number of the scans in which the Bluetooth transmission was detected. In instances that a detected Bluetooth transmission is a page, a Bluetooth transceiver in the wireless communication device may be powered up and/or enter a page scanning mode. The scans may be performed by a wireless local area networking receiver within the wireless communication device.

摘要： Aspects of a method and system for simultaneous signal transmission on multiple selected frequencies may include generating from a single baseband signal, a plurality of radio frequency transmission signals each at a different radio frequency, wherein the single baseband signal comprises an in-phase signal component and/or a quadrature signal component. The single baseband signal, to generate said plurality of radio frequency transmission signals, may be modulated in a single radio frequency transmission chain, the radio frequency transmission chain comprising intermediate frequency modulation and radio frequency modulation. The plurality of radio frequency transmission signals may be a radio frequency signal and a corresponding image frequency signal, based on the intermediate frequency modulation and the radio frequency modulation. The signals resulting from the intermediate frequency modulation and the radio frequency modulation may be filtered to preserve the radio frequency signal and the corresponding image frequency signal.

摘要： Aspects of a method and system for using a frequency locked loop LOGEN in oscillator systems may include generating an oscillating signal via one or more circuits comprising a feedback loop. The generation may be controlled by enabling or disabling the feedback loop, based on the generated oscillating signal. The one or more circuits may comprise a frequency-locked loop (FLL) that may enable the generation of the oscillating signal. The frequency-locked loop may comprise a voltage-controlled oscillator. The feedback loop may be disabled when an estimated frequency difference between a reference signal and a feedback signal may be less than or equal to a specified threshold. The feedback loop may be enabled when an estimated frequency difference between a reference signal and a feedback signal may be greater than a particular threshold.

摘要： Aspects of the invention may comprise managing operations of BLE interfaces and/or other radio interfaces in a wireless device to mitigate interference to communication via the BLE interfaces by the other radio interfaces. Operating parameters may be communicated between the BLE interfaces and the other radio interfaces to enable mitigating the interference to the BLE interfaces, and at least some of the BLE interfaces and/or the other radio interfaces may be configured based on the communicated operating parameters. The operating parameters may comprise adaptive frequency hopping (AFH) maps that may be adjusted to prevent use of common and/or used channels. The communication device may detect energy associated with BLE communication via scan of all or some of channels used for BLE communication. BLE communication may be predicted based on monitoring of frequency bands used during BLE communication, and/or monitoring of events that may trigger and/or occur during BLE communication.
