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： 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： 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.
