摘要： This disclosure is directed to a wireless device with a suppressor that couples to the aggressor signal of a frequency source to generate a cancelling signal for suppressing spurs resulting from operation of the frequency source. The amplitude and phase delay of the cancelling signal are adjusted to optimize the cancellation of the spur. Preferably, a calibration routine is performed to establish appropriate delay and amplitude values to cancel the spurs occurring at each device gain setting.

摘要： A device and method for adjusting transmit power in a wireless communication device. The wireless communication device comprises a transmitter having a power amplifier, wherein the amplifier may introduce distortion into the transmit signal. The method may periodically determine an error vector magnitude (EVM) level in the transmitter of the wireless communication device. The EVM level may be determined based on differences between an ideal transmit signal without amplification, and an actual transmit signal with amplification. The method may then adjust one or more transmit gain settings of at least one gain stage of the wireless device based on the measured EVM level in the transmitter. In one embodiment, as the EVM increases, indicating that more distortion is being introduced, the method may reduce the gain settings of the gain stage(s) to reduce this distortion. If the EVM decreases, the method may increase the gain of the gain stage(s).
摘要翻译：一种用于在无线通信设备中调整发射功率的设备和方法。无线通信设备包括具有功率放大器的发射机，其中放大器可以将失真引入到发射信号中。该方法可以周期性地确定无线通信设备的发射机中的误差向量幅度（EVM）。 EVM电平可以基于没有放大的理想发送信号和具有放大的实际发送信号之间的差异来确定。该方法然后可以基于发射机中测量的EVM电平来调整无线设备的至少一个增益级的一个或多个发射增益设置。在一个实施例中，随着EVM增加，指示正在引入更多的失真，该方法可以减小增益级的增益设置以减少该失真。如果EVM降低，则该方法可以增加增益级的增益。

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.

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 polar transmitter includes a phase monitoring unit for monitoring input modulating data. When a phase transition exceeds a phase transition threshold, the phase monitor unit can signal an amplitude negation unit to invert the amplitude data coupled to the polar amplifier. The phase monitoring unit can also add an offset to the phase data that is provided to a frequency synthesizer. In another embodiment, when the phase transition threshold is exceeded, the phase monitoring unit can trigger inverting differential frequency data coupled to the polar amplifier. In one embodiment, the phase offset and the amplitude negation are applied until a second phase transition value exceeding the phase transition threshold is detected. If such an event is detected, then the input amplitude data is no longer inverted and the phase offset value is no longer added to the modulating data.
