Abstract: A communications subsystem for a wireless device for correcting errors in a reference frequency signal. The communications subsystem comprises a frequency generator for generating the reference frequency signal and a closed loop reference frequency correction module that generates a reference frequency adjustment signal for correcting the reference frequency signal when the communications subsystem operates in closed loop mode. The subsystem further includes an open loop frequency correction means that that samples values of the reference frequency adjustment signal during the closed loop mode and generates a frequency correction signal for correcting the reference frequency signal when the communications subsystem operates in a mode other than closed loop mode.

Abstract: A CT device and method based on motion compensation are proposed. The present invention obtains motion parameters of a target object by using a stereo-vision-based motion measurement system, and then implements motion compensation through the technology based on reconstructed image matrix transformation, thereby obtaining a clear 2D/3D CT image while eliminating motion artifacts. The present invention can effectively eliminate motion artifacts caused by the scanned object's own motions in the CT scanning, and can be easily embedded into the existing CT scanning equipments. The present invention can improve quality of the CT images, and is especially important for CT imaging of some special groups of people that can not control their own motions, such as Parkinson's patients, infants, living mouse and so on. It can also improve ultra-high-resolution imaging of human body.

Abstract: A peak to average power ratio signal is generated from a first mapping function that selects the peak to average power ratio signal that corresponds to the data rate or data format of the signal to be transmitted. The selected peak to average power ratio signal is summed with a desired average transmit power signal. The resulting summation signal is input to a second effectively continuously valued mapping function comprising a table that has a plurality of power amplifier control signal values each with a corresponding peak transmit power. Each peak transmit power signal value results in a power amplifier control signal value that achieves the best possible transmitter power efficiency while still meeting out of band spurious emissions and waveform quality requirements. The summation signal value maps to one of the power amplifier control signal value that is then used to adjust a parameter such as bias of the power amplifier.

Abstract: A method is performed by a wireless device. The method includes (a) preselecting a set of the base stations; (b) selecting a reverse link cost according to a preselected reverse link cost metric; (c) selecting a base station from the set of base stations; and (d) sending a probe signal at the selected reverse link cost to the selected base station. If a response is not received from the selected base station within a preselected time period and not all the base stations have been sent a probe signal at substantially the selected reverse link cost, then steps (c) through (d) are repeated with a different one of the base stations at substantially the selected reverse link cost. If a response is received from the selected base station within the timeout period, then the responding base station is selected to provide access to the wireless network.

Abstract: A method and apparatus for estimating oscillator signal variation due to temperature and for providing an estimated frequency to a GPS receiver in order to assist the GPS receiver to acquire the signals quickly is disclosed. A temperature sensor is closely thermally coupled with the crystal oscillator in the GPS receiver and during GPS tracking mode, when the error in the oscillator signal is known with precision, outer bounds of TCXO frequency at given temperatures are maintained, which may correspond to rising and falling temperature conditions. During acquisition mode, an estimated frequency value is provided to the GPS receiver based on a determined average of these bounds. Optionally, an uncertainty factor associated with the frequency estimated may also be provided. The two bounds take into account the hysteresis effects of the oscillator signal drift due to temperature so that a more accurate initial frequency estimate can be provided to the GPS receiver, thus reducing its average time to first fix.
