For example, a Bluetooth (BT) apparatus may include a System on Chip (SoC), the SoC including an interface to a BT Lower Medium Access Control (MAC) (L-MAC) external to the SoC; and a BT Upper MAC (U-MAC) to generate setup information to configure one or more BT activities by the BT L-MAC, and to send the setup information to the BT L-MAC via the interface, the setup information to configure one or more wakeup criteria for the BT L-MAC to wake up the BT U-MAC, the one or more BT activities including at least a BT scan, wherein the BT U-MAC is configured to enter a power save mode and to wake up from the power save mode based on receipt of a wakeup indication from the BT L-MAC via the interface to the BT L-MAC.

Digital logic circuitry is disclosed. The circuitry includes local oscillator drift and phase compensation logic that compensates the frequency drift and the phase noise of a local oscillator generated by a digitally controlled oscillator.

A system and method for obtaining the bearing angle of radio frequency is utilized in a direction finding system to determine the signal of interest. The system utilized an adaptive interferometric processor to null out modulation occurring due to commutation between the antenna elements. Through this system the bearing angle can be determined accurately and efficiently.

A system for reducing co-channel interference includes a power spectrum analyzer which provides a spectral signal representative of an intermediate frequency signal from the receiver of a direction finding system. The system further includes threshold/window logic that, responsive to the comparison of threshold levels and spectral windows to the interfering signals, will provide stop and continue signals to an integrator. The integrator receives signals from the direction finding system and stops and starts integration of the output signal responsive to the threshold logic. In so doing, co-channel interference is substantially reduced.

An antenna configuration system for determining the bearing angle of a radio frequency signal includes a plurality of loop antennas and at least one sense antenna. Through the utilization of combining networks with the loop antennas, in-phase and out-of-phase output signals are summed with the signal from the one sense antenna. The summed signal is sent to an adaptive processing system to allow for the determination the bearing angle of the radio frequency signal.
