摘要： A wireless device includes a functional unit, a wireless transceiver, an antenna and a clock. The wireless transceiver and antenna are coupled to the functional unit. The clock is coupled to the functional unit and the wireless transceiver. The clock is generates a clock signal. The wireless device is coupled wirelessly to a wireless slave device. The functional unit is configured to determine an amount of time since a last keep alive transmission with the slave device has occurred based on the clock. The functional unit determines a number of keep alive transmissions to transmit to the slave device, and appropriate transmission times for the keep alive transmissions relative to a next scheduled keep alive transmission time, based on the determined amount of time since the last keep alive transmission. The functional unit begins successive transmission of the keep alive transmissions to the slave device per the transmission times.

摘要： Wireless devices may contain multiple radio transceivers, each conforming to different communication protocols. A first transceiver conforming to a first communication protocol in a first wireless device may be able to receive, detect, and/or decode messages transmitted by a second transceiver in a second wireless device conforming to a second communication protocol. The first transceiver may communicate received, detected, and/or decoded information to a different transceiver in the same first wireless device, thus enabling the collocated transceivers to work in concert efficiently. A wideband transceiver using a set of multiple sub-channels in parallel may receive, detect, and/or decode messages transmitted by a narrowband transceiver using a set of multiple channels serially, thereby reducing scan time and power consumption.

摘要： A Viterbi decoding system interprets bits in received QAM constellations as many-valued parameters rather than binary valued parameters. It performs the Viterbi algorithm using these many-valued parameters to provide results superior to hard decision decoding. Rather than applying a hard 0-1 function to the QAM data, the system uses a non-stepped linear or curved transfer function to assign values to the bits. In another aspect, a system differentiates between data bits based on their estimated reliability, giving more emphasis to decoding reliable bits than unreliable bits using any of a variety of techniques. By differentiating between good and bad bits and de-emphasizing or ignoring unreliable bits, the system can provide a significant reduction in uncorrectable errors and packet loss.

摘要： Systems and methods for passively calibrating and correcting for I/Q mismatch in a quadrature receiver without the necessity of modifying the analog portion of the receiver by adding calibration signals or correction circuitry are presented. The passive I/Q mismatch calibration system proceeds using normally received incoming transmitted data signals to obtain statistical information on which to base I/Q mismatch compensation factors. The I/Q mismatch compensation factors can be used to adjust the magnitude and phase response in the time domain or the frequency domain, the analog or the digital portion of the receiver. Depending on the embodiment, the passive I/Q mismatch calibration system can calibrate frequency dependent gain or magnitude imbalance, frequency independent magnitude imbalance, frequency dependent phase imbalance, and frequency independent phase imbalance or combinations or these.

摘要： A modulation system comprising a signal processing unit and a modulator. The signal processing unit may generate a low frequency modulator signal, a high frequency modulator signal, and a modulator amplitude control signal. The modulator may generate a modulated signal for transmission via a wireless network based, at least in part, on the low frequency modulator signal, the high frequency modulator signal, and the modulator amplitude control signal. The signal processing unit comprises a delay compensation unit for delaying the generation of the high frequency modulator signal and the modulator amplitude control signal based, at least in part, on signal generation and modulation path delays associated with the low frequency modulator signal to substantially align the modulator signals at the output of the modulation system.

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： A radar detection technique in a WLAN device can include a short pulse detection technique and a long pulse detection technique that can be performed using multiple receive chains. Short pulse detection is particularly effective when the incoming signal includes one or a limited number of main pulses and some residual pulses. In contrast, long pulse detection is particularly effective when the incoming signal is longer, thereby allowing various characteristics of the incoming signal to be accurately measured.

摘要： Bluetooth file transfers using FTP do not provide upper-layer reliability checking and rely on the Bluetooth device physical layer providing reliable data to upper layers of a Bluetooth stack. However, reliability checks implemented by the physical layer are typically not very robust and in some cases may fail to detect errors, thus may provide corrupted data to the upper layers for further processing and may result in data corruption/transfer failure. Non-FTP Bluetooth file transfers are typically more robust when it comes to reliability checking because of upper layer reliability checks. Functionality can be implemented to vary packet transmission parameters depending on a Bluetooth profile implemented on a communication link. A packet error rate of received packets can be compared against a different set of thresholds depending on whether the Bluetooth profile is an FTP profile. Appropriate values of packet transmission parameters can be selected based on the above comparison.
摘要翻译：使用FTP的蓝牙文件传输不提供上层可靠性检查，并依靠蓝牙设备物理层向蓝牙堆栈的上层提供可靠的数据。然而，由物理层实现的可靠性检查通常不是非常强大的，并且在某些情况下可能无法检测到错误，因此可能会向上层提供损坏的数据以供进一步处理，并可能导致数据损坏/传输失败。由于上层可靠性检查涉及到可靠性检查，非FTP蓝牙文件传输通常更加强大。可以实现功能以根据在通信链路上实现的蓝牙配置来改变分组传输参数。接收到的分组的分组错误率可以与不同的阈值集进行比较，这取决于蓝牙配置文件是否是FTP配置文件。可以基于上述比较来选择适当的分组传输参数值。
