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： 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。

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： 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： Methods of calibrating and operating a switching power supply in an electronic system are disclosed. A switching power supply is calibrated to determine a switching frequency. Harmonic frequencies that are multiples of the switching frequency are determined. A further determination is made as to whether any of the harmonic frequencies falls within one of one or more frequency bands of interest. A second switching frequency is determined such that none of its corresponding harmonic frequencies falls within a frequency band of interest. During operation of the system, the switching power supply is configured to operate at the second switching frequency if operation occurs within one of the frequency bands of interest.

摘要： This disclosure is directed to wireless communication systems having a receiver configured to search for transmitted packets using a single chain and then receive the transmitted packets using multiple chains. Such receivers feature a chain controller that operates a single chain during search mode and turns on additional chains after packet detection. As will be appreciated, the techniques of this disclosure take advantage of the structure of the mixed mode data packet preamble to allow multiple chains to be brought on line after detection of a packet by a single chain.

摘要： Arbitrary phase variations of a shared frequency synthesizer can be calibrated using a reference harmonic each time the shared frequency synthesizer is allocated to a network device to enable one frequency synthesizer to be shared between multiple network devices. On determining that the shared frequency synthesizer has been allocated to the network device, an output frequency of the shared frequency synthesizer can be aligned with a predetermined reference frequency that is associated with an operating frequency band of the network device. A phase correction factor associated with the shared frequency synthesizer can be calculated from a signal calculated based, at least in part, on the output frequency of the shared frequency synthesizer and the predetermined reference frequency. The phase correction factor is applied to a signal received at the network device to correct a phase error associated with the shared frequency synthesizer.
