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： A symbol error detector can be configured to detect symbol errors of a Bluetooth enhanced data rate (EDR) packet without relying solely on a CRC error detection mechanism. After a phase of a current symbol is demodulated to determine a demodulated current symbol, the phase of the demodulated current symbol can be subtracted from the phase of the current symbol prior to demodulation to yield a phase error. The phase error can be compared against a phase error threshold to determine a potential unreliability of the demodulated current symbol. The phase error being greater than the phase error threshold can indicate that the demodulated current symbol may be unreliable. Accordingly, a symbol error notification can be generated to indicate that the demodulated current symbol may be unreliable.
摘要翻译：符号错误检测器可被配置为检测蓝牙增强数据速率（EDR）分组的符号错误，而不依赖于CRC错误检测机制。在解调当前符号的相位以确定解调的当前符号之后，可以在解调之前从当前符号的相位中减去解调的当前符号的相位，以产生相位误差。相位误差可以与相位误差阈值进行比较，以确定解调电流符号的潜在不可靠性。相位误差大于相位误差阈值可以指示解调的当前符号可能不可靠。因此，可以生成符号错误通知以指示解调的当前符号可能不可靠。

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： Performing wireless communication using first and second wireless communication protocols. The first and second wireless communication protocols may operate in a common communication medium. The wireless communication may be performed using the protocols over the common communication medium, e.g., in a time sharing fashion. Properties of voice traffic on current frames of the second wireless communication protocol may be measured. The method may further include predicting whether one or more subsequent frames of the second wireless communication protocol will have voice traffic. If the prediction indicates that the one or more subsequent frames of the second wireless communication protocol will not have voice traffic data may be transmitted using the first wireless communication protocol on the common communication medium during a subsequent second wireless communication protocol time slot.
