摘要： Controlling power consumption in a wireless device. The wireless device may include first wireless protocol circuitry. The first wireless protocol circuitry may be configured to receive and process first signals according to a first wireless protocol. The wireless device may include a power controller coupled to the first wireless protocol circuitry. The power controller may be configured to control power consumption of elements of the first wireless protocol circuitry based on a current state. More specifically, in response to the first wireless protocol circuitry being in a listening state, the power controller may be configured to lower power consumption of one or more first elements of the first wireless protocol circuitry. Additionally, in response to the first wireless protocol circuitry being in a receiving state, the power controller may be configured to return power consumption of the one or more first elements to a higher power level.

摘要： A method and apparatus for wirelessly transmitting real-time data streams is described. To ensure continuous data flow, fast diversity and slow diversity can be used. Fast diversity chooses a receive antenna based on received signal parameters, such as signal strength, during the transmission header and prior to information transfer. Slow diversity stores received signal parameters from previous packets, associates the parameters with a selected antenna, and uses the parameter history to denote a “default” antenna. Additionally, receive and/or transmit beam forming can be used to maintain continuous communication between stations. Beam forming, which combines antenna signals to maximize performance, is possible when at least two transmit/receive signal processing chains are available.

摘要： Determining if a packetized wireless signal is present on a wireless communication medium. A first signal may be received from the wireless communication medium. A correlation of the first signal may be performed using a delayed version of the first signal to produce a correlation result. The delayed version may be delayed by a time period corresponding to a packet structure of a wireless communication protocol used by signals transmitted on the wireless communication medium. It may be determined if the correlation result indicates presence of a packetized wireless signal in the first signal. The packetized wireless signal may have the packet structure of the wireless communication protocol. If the correlation result does not indicate presence of the packetized wireless signal in the first signal, wireless communication may be performed over the wireless communication medium.

摘要： Performing wireless communication using first and second wireless communication protocols. The first and second wireless communication protocols may operate in a common communication medium. The wireless communication may be performed using the protocols over the common communication medium, e.g., in a time sharing fashion. Properties of voice traffic on current frames of the second wireless communication protocol may be measured. The method may further include predicting whether one or more subsequent frames of the second wireless communication protocol will have voice traffic. If the prediction indicates that the one or more subsequent frames of the second wireless communication protocol will not have voice traffic data may be transmitted using the first wireless communication protocol on the common communication medium during a subsequent second wireless communication protocol time slot.

摘要： System and method for operating a wireless narrowband receiver. A signal may be received on a channel of the wireless narrowband receiver. At least a portion of the signal may be received from a first wireless narrowband transmitter. The wireless narrowband receiver may implement an adaptive frequency hopping algorithm. It may be determined if interference is present on the channel and one or more errors are detected in receiving the signal. In response to determining that interference is present on the channel and one or more errors are detected in receiving the signal, received signal strength of one or more neighboring frequencies of the channel may be measured, and the resulting measurements may be stored in a memory. The measurements may be used to determine interference sources interference on the channel.

摘要： A system for detecting the level of the noise floor due to circuit noise as seen at the ADC for a wireless receiver. The system measures power after digitizing and filtering, and subtracts off any variable gain used in the analog front end to determine differentially the size of the signal at the antenna. The system further differentially detects the signal size of any incoming signal at the antenna in a similar fashion, and determines its size relative to the measured noise floor. If the level of the circuit noise of the receiver is known absolutely, the absolute signal size of the incoming signal can likewise be determined with this inventive method and system.

摘要： System and method for performing clear channel assessment for simultaneous transmission in a device implementing multiple wireless protocols. The system may include first and second wireless protocol circuitry configured to generate first and second signals, respectively, for wireless transmission according to first and second wireless protocols, respectively. A first in-band signal strength threshold and a second in-band signal strength threshold may be maintained by the first wireless protocol circuitry. It may be determined whether the first or second in-band signal strength threshold should be used in performing the clear channel assessment. Clear channel assessment may be performed using the determined in-band signal strength threshold. Performing clear channel assessment may include comparing an ambient signal strength on a channel with the determined in-band signal strength threshold. The first wireless protocol circuitry may be configured to determine whether to wirelessly transmit first signals based on the clear channel assessment.

摘要： A Bluetooth paging procedure can implement a mechanism for predicting a Bluetooth paging channel in a paging channel hopping sequence. One or more Bluetooth paging channels, on which one or more page requests intended for a Bluetooth device were received, are determined from a plurality of Bluetooth communication channels. One of a plurality of paging channel hopping sequences associated with the Bluetooth device that comprises each of the one or more determined Bluetooth paging channels is identified. A time delay associated with determining a target Bluetooth paging channel from the plurality of Bluetooth communication channels on which to transmit a page response is determined. The target Bluetooth paging channel is determined based, at least in part, on the identified one of the plurality of the paging channel hopping sequences and the time delay.

摘要： A wireless communication device includes a core logic, first and second transceiver chains, first and second antennas, and an interference processor. The core logic is coupled to both the first and second transceiver chains, which in turn are coupled to the first and second antennas, respectively. The interference processor is coupled between the first and second transceiver chains. To calibrate circuitry within the first transceiver chain using first signals generated in the first transceiver chain while the second transceiver chain is transmitting second signals via the second antenna, the interference processor connects the transmit circuit of the second transceiver chain to the receive circuitry of the first transceiver chain to form an interference feedback path that can be used to compensate for unwanted components of the second signal undesirably picked up by the first antenna.
