摘要： A battery (102) powers a wireless telephone's power amplifier (106) through a Switch Mode Power Supply (SMPS) (104). The SMPS has a capacity lower than the maximum power requirements of the amplifier. When a controller (116) senses that an amplifier power-requirement threshold has been exceeded, it closes a switch (114) parallel to the SMPS, allowing power to flow from the battery to the amplifier without passing through the SMPS. This architecture allows the use of a smaller SMPS, and eliminates SMPS-generated noise to the amplifier when the amplifier is least able to tolerate such noise, namely, under high power conditions.

摘要： A wireless device is equipped with multiple (e.g., two) antennas, which may be of different designs. Each antenna interacts with the wireless environment in a different manner and achieves different scattering effect. The wireless device has one transmit signal path for each antenna. Each transmit signal path generates an RF output signal for transmission from the associated antenna. The wireless device controls the operation of one or more transmit signal paths to achieve a larger received signal level at a receiving base station. The wireless device may (1) autonomously adjust the transmit signal path(s) without relying on any feedback from the base station or (2) adjust the transmit signal path(s) based on transmit power control (TPC) commands received from the base station. The wireless device may selectively enable and disable each transmit signal path, vary the phase and/or gain of each transmit signal path, and so on.

摘要： In an exemplary application, an apparatus according to a disclosed embodiment receives a radio frequency signal and outputs an intermediate frequency signal. Rejection of image components in the intermediate frequency signal is obtained without the need to preprocess the radio frequency signal with an image reject filter. Such an apparatus may also exhibit an image rejection performance that is robust to frequency deviation of a local oscillator.

摘要： Techniques to reduce intermodulation distortion at the output of an active circuit having even-order and odd-order nonlinearities. The IM3 products generated by the even-order nonlinearity of the active circuit are canceled against the IM3 products generated by the odd-order nonlinearity. The amplitude and phase of the IM3 products can be manipulated by adjusting either the source or load impedance, or both, of the active circuit. The amplitude and phase of the IM2 products generated by the even-order nonlinearity can be manipulated by adjusting the impedance of the active circuit at sub-harmonic and second harmonic frequencies (i.e., the frequencies of the IM2 products). The amplitude and phase of the IM3 products generated by the odd-order nonlinearity can be manipulated by adjusting the impedance of the active circuit at the fundamental frequency. By properly tuning or "matching" the impedance of either the source or load, or both, of the active circuit at either the sub-harmonic or second harmonic frequency, or both, the amplitude and phase of the IM2 products can be adjusted such that the IM3 products resulting from the even-order nonlinearity approximately cancel the IM3 product(s) resulting from the odd-order nonlinearity.

摘要： This disclosure describes companded transmit path techniques that may be implemented in a wireless communication device to reduce power consumption and possibly simplify signal modulation. In accordance with this disclosure, in phase (I) and quadrature phase (Q) components of a transmit waveform are compressed at baseband, and an emphasis envelope is generated to represent this compression. The compressed I and Q components are then converted to analog signals and processed. This analog processing may include the mixing process in which the compressed I and Q signals are modulated onto a carrier waveform. The emphasis envelope signal is then used to expand the modulated waveform.

摘要： To reduce power consumption, receiver circuit blocks within a wireless device are biased with less current whenever possible while still achieving the desired performance. The receiver circuit blocks may include a voltage controlled oscillator (VCO) that generates an oscillator signal used for frequency downconversion of a received signal from the forward link, a low noise amplifier (LNA) that amplifies the received signal, and a mixer that frequency downconverts the received signal. The VCO may be biased with less current if phase noise performance is less stringent, e.g., when (1) the wireless device is not transmitting on the reverse link, (2) a large amplitude jammer is not detected, and/or (3) the received signal level is sufficiently high. The bias currents of other receiver circuit blocks may also be adjusted based on transmitter activity, detected jammer, and/or received signal level.

摘要： A system and method in which the position update rate is adaptively modified, based on previous position measurements. By adjusting the update rate based on velocity predictions from two or more position fixes, a lower update rate may be used without exceeding the maximum error. Lowering the update rate reduces power consumption in the UE, providing longer battery operation. The updating method may comprise periodically repeating the velocity prediction and periodically adjusting the update rate responsive thereto. The update rate may be adjusted using additional information such as an acceleration prediction, a minimum update rate, or a preferred error. In some embodiments a model for user movement may be used to provide more accurate predictions, for example, stationary, walking, jogging, city driving, and freeway driving. The updating method may comprise receiving user input regarding the maximum position error.
