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： 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 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.

摘要： An adaptive frequency hopping system and method uses two separate channel masks in an electronic device with collocated frequency hopping and single frequency systems to permit simultaneous transmissions by both systems without reducing a rate of data communication through the single frequency system. A first channel mask, corresponding to a transmission mask, and a second channel mask, corresponding to a reception mask, are separated from a carrier frequency used by the single frequency system, and optionally from two different carrier frequencies used by two different single frequency systems, by a selected magnitude of frequency difference. The selected magnitude of frequency difference may optionally be reduced to permit a channel mask to contain a minimum selected number of frequency hopping channels.

摘要： Interference can impair communications of collocated wireless devices or wireless devices communicating in close proximity to each other. In implementations where the communications of one wireless device have a higher priority as compared to the communications of the other wireless device, the low priority communications should not impair or interfere with the high priority communications. Functionality can be implemented to control when the low priority wireless device transmits based on a current state (e.g., active/inactive) of the collocated high priority wireless device, a frequency separation between communication channels of the wireless devices, strengths of signals received by the wireless devices, etc. Transmit power of the low priority wireless device may be controlled so that the low priority communications do not impair the high priority communications.

摘要： In some wireless local area networks (WLANs), signals of different modulation types and rates can be received. To operate optimally, the gain of an amplifier in a receiver can be set based on a specific modulation type and rate. For example, the gain of a receive path amplifier can be changed based on one or more unique identifying characteristics in a received data packet. Once the unique identifying characteristics are located, they can be analyzed to determine which modulation type and rate are represented. The appropriate gain of the amplifier can be set based on the modulation type and rate. Advantageously, subsequent data symbols can be amplified with the set gain, thereby ensuring that the receiver optimally receives those data symbols.

摘要： A spur detection and spur cancellation apparatus in a multiple sub-carrier digital communication receiver includes a spur detection block that estimates, using one or more Fourier transforms, a frequency location of a narrowband interference spur in a received digital signal that includes a plurality of sub-carriers, and a spur cancellation block that attenuates the estimated narrowband interference spur. The spur detection block may use a fast Fourier transform (FFT) and/or a discrete Fourier transform (DFT) to locate a frequency and to measure a discrete power spectra of the narrowband interference spur. A channel state information block in the receiver may adjust a channel state information metric based on the located frequency and/or the measured discrete power spectra of the narrowband interference spur.
