摘要： An apparatus for processing a Bluetooth signal advantageously mixes down a received RF signal to an IF signal wherein one band-edge of the spectrum of the IF signal may be approximately 0 Hz. In one embodiment, the IF signal may be digitized, decimated and filtered before being processed into a baseband signal. The baseband signal may be processed by a cordic (COordinate Rotation DIgital Computer) processor to transform the baseband signal from rectangular to polar coordinates. A phase signal from the cordic processor may be used to determine transmitted Bluetooth data symbols. The apparatus may advantageously use less area than traditional Bluetooth receivers.

摘要： One embodiment of a DPSK receiver includes an ADC, a down-sampler, and a timing tracker. The ADC samples a received DPSK signal providing sub-samples of a digital signal. The timing tracker examines differences between amplitudes of currently selected sub-samples and sub-samples before and after the currently selected sub-samples. The differences may indicate a timing adjustment may be made to the digital signal. The timing tracker may change the timing of the digital signal by modifying the configuration of the down-sampler. Additionally, the timing tracker may also correct phase errors introduced by configuration changes of the down-sampler.

摘要： A wireless device that can process signals according to multiple wireless protocols simultaneously and without signal loss. The wireless device may comprise an antenna and first and second wireless protocol circuitry. The first wireless protocol circuitry comprises a shared gain element that amplifies signals that are processed by each of the first and second wireless protocol circuitry. Since the third signals are amplified by the shared gain element prior to being split out to the respective protocol circuitry, the first and second portions of the amplified third signals do not have significant signal loss relative to the third signals provided by the antenna. Thus the wireless device can receive and process wireless signals according to both the first and second protocols simultaneously without any significant signal losses due to splitting of the receive signal.
摘要翻译：一种无线设备，可以同时处理多个无线协议信号，无信号丢失。无线设备可以包括天线和第一和第二无线协议电路。第一无线协议电路包括共享增益元件，其放大由第一和第二无线协议电路中的每一个处理的信号。由于第三信号在被分配到相应协议电路之前被共享增益元件放大，所以放大的第三信号的第一和第二部分相对于由天线提供的第三信号不具有显着的信号损耗。因此，无线设备可以同时接收和处理根据第一和第二协议的无线信号，而不会由于接收信号的分离而导致任何显着的信号损失。

摘要： A transceiver including a transmit modulator and a receiver. The modulator may accept a channel selection input, a first modulation input, a second modulation input, and an amplitude input. During transmit time slots, the modulator may generate a modulated output having a carrier frequency selected by the channel selection input. The carrier frequency may be frequency modulated by the first modulation inputs, phase modulated by the second modulation input, and amplitude modulated by the amplitude input. During receive time slots, the modulator may generate a carrier frequency selected by the channel selection input and offset by the first modulation input. The modulator may alternate between providing modulated transmit signals during transmit time slots and providing a local oscillator for the receiver during receive time slots.

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。
