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.
摘要翻译：用于处理蓝牙信号的装置有利地将所接收的RF信号与IF信号相混合，其中IF信号的频谱的一个带边可以为大约0Hz。在一个实施例中，IF信号可以在被处理成基带信号之前被数字化，抽取和滤波。基带信号可以由Cordic（Coordinate Rotation DIgital Computer）处理器处理，以将基带信号从矩形变换为极坐标。可以使用来自Cordic处理器的相位信号来确定所发送的蓝牙数据符号。该装置可以有利地使用比传统蓝牙接收机更少的面积。

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 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.

摘要： Redundancies of power amplifiers (PAs) or low noise amplifiers (LNAs) at the front end of an RF device are used to reduce losses that typically occur at a diversity switch. A signal designator can advantageously be used to select designated signals, which are provided to the PAs for transmitting or provided by the LNAs during receiving.
