摘要： Methods and systems for wireless communication are disclosed and may include sweeping a signal detection frequency one or more times across a plurality of steps in a frequency range. The measured signal strength at each step may be compared to a threshold, and a status may be stored, which may depend on the presence of a measured signal strength above threshold. The detection frequency may be swept utilizing a voltage controlled oscillator, which may be tuned via a control voltage and/or calibration capacitors. Steps may be skipped when a measured signal strength may be greater than the threshold, and may occur after multiple above threshold measurements. The steps may have variable frequency width, and the range may include the Bluetooth band from 2.40 GHz to 2.48 GHz. The frequency may be swept over a subset of the Bluetooth band, and may be swept on a periodic basis.

摘要： Methods and systems for collaborative coexistence of Bluetooth and WiMax are disclosed. Aspects of one method may include a packet traffic arbiter (PTA) in a mobile terminal that arbitrates among requests to transmit from one or more communication devices collocated in the mobile terminal. The communication devices may comprise, for example, a WLAN communication device, a WiMax communication device, and/or a Bluetooth communication device. The arbitration may be based on, for example, whether a packet will be received by one of the plurality of collocated communication devices at a time of transmission of the present data packet and/or a priority for data to be transmitted. An exemplary scenario may be where a Bluetooth headset may be used for communication over a WiMax voice connection. One arbitration method may comprise allowing the WiMax packet to be transmitted, and replacing the received Bluetooth packet with data indicating silence. Another method may comprise not allowing transmission of the present WiMax packet. Rather, the present WiMax packet and a subsequent WiMax packet may e transmitted at the next transmission period.

摘要： An embedded processor system including at least one gated power unit including an internal ROM and a power controller that provides one or more gated power signals to selectively provide power to each gated power unit. The power controller provides a gated clock signal to the embedded processor to selectively control power consumption of the processor. The power controller powers down each gated power unit after freezing the processor and then powers up each gated power unit before reactivating the processor. The embedded processor system may include isolation circuitry, such as clamp circuitry or the like, that is operative to minimize current flow into each gated power unit when powered down. The gated power units may include a static function. The ROM of an embedded ROM-based microprocessor system is powered down when the microprocessor is idle to reduce or otherwise eliminate intrinsic leakage.

摘要： A radio receiver is described that processes multiple wireless standards using a single antenna according to embodiments of the invention. The radio receiver includes a single antenna, and a low noise amplifier that is connected to the antenna, without an intervening power divider or power splitter. The output of the low noise amplifier feeds multiple wireless receivers in a parallel arrangement that are operating according to different communications standards, including for example a Bluetooth receiver, and a WLAN 802.11 receiver. Additional wireless standards and their corresponding receivers could be added as well. The input impedance of the low noise amplifier defines the impedance seen by the antenna, regardless of which operational standard is actually in use. Since the input impedance of the low noise amplifier is substantially independent of whether the Bluetooth or WLAN paths are ON or OFF, simultaneous operation can be accomplished.

摘要： Certain embodiments of the invention may be found in a method and system for collaborative coexistence between Bluetooth and IEEE 802.11 g with both technologies integrated onto an SOC device. In a single integrated circuit (IC) that handles Bluetooth and WLAN technologies, a WLAN priority level may be selected for WLAN transmissions and a Bluetooth priority level may be selected for Bluetooth transmissions. The WLAN and Bluetooth priority levels may be selected from a plurality of priority levels. A packet transfer scheduler (PTS) may schedule the transmission of WLAN and Bluetooth signals in accordance with the selected priority levels. In some instances, the PTS may promote or demote the priority levels for WLAN and/or Bluetooth transmissions based on traffic needs.

摘要： Aspects of a method and system for a radio data service (RDS) demodulator for a single chip integrated Bluetooth and frequency modulation (FM) transceiver and baseband processor are presented. Aspects of the system may include circuitry on a single chip that enables demodulation of an RDS signal, filtering of the RDS signal, and detection of binary bits in the filtered RDS signal. The filtered RDS signal may be generated by filtering the RDS signal based on a raised cosine filter, or a doublet filter. In general, the RDS signal may also be filtered by a filter that is a first, or greater derivative of a Gaussian filter in either the time or frequency domain. Aspects of the method may include demodulating the RDS signal, filtering the RDS signal, and detecting binary bits in the filtered RDS signal.

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.
