摘要： A method and apparatus for locating position of a satellite signal receiver is described. In one example, groups of pseudoranges from the satellite signal receiver to a plurality of satellites are determined at a respective plurality of times. The groups of pseudoranges are transmitted to a server, where a position of the satellite signal receiver may be determined using the groups of pseudoranges. In another example, a plurality of groups of pseudoranges are applied to a time-based filter located in the server. The position of the satellite signal receiver is derived from the time-based filter.

摘要： A method and apparatus for using a conventional oscillator in a cellular telephone transceiver as a source of a reference signal for a GPS receiver. In one embodiment, the method comprises using a voltage-controlled oscillator (nullVCXOnull) within a cellular telephone transceiver to generate a reference frequency signal for the GPS receiver. Circuitry within the telephone transceiver generates a frequency error signal. Both of these signals are coupled to GPS circuitry and used to control a carrier numerically controlled oscillator (nullNCOnull) and a code NCO. The NCOs produce a tuning signal and a timing signal, respectively. The GPS circuitry uses the NCO generated signals to process GPS signals.

摘要： A method and apparatus for correlating a satellite signal with a reference code is described. In an example, samples of a satellite signal having a repeating code are received. At least one fast convolution between the samples and the pseudorandom reference code is performed. A correlation peak is detected within a result of the at least one fast convolution. A code phase of the repeating code relative to the pseudorandom reference code is estimated at the correlation peak. The samples are then correlated with the pseudorandom reference code using the code phase as an initial value.

摘要： A method and apparatus for performing timing synchronization in a mobile device. The method and apparatus include a wireless transceiver having a first oscillatory signal generator (OSG) and a Global Position System (GPS) receiver. The GPS receiver includes a second oscillatory signal generator coupled to a counter for receiving a first clock signal from the first OSG and a second clock signal from the second OSG. Additionally, a GPS signal processor is coupled to the counter. The counter provides a relative offset signal between the first and second oscillatory signal generators to the GPS signal processor for adjusting a pseudo-range model.

摘要： Method and apparatus for a GPS device that uses at least one cellular acquisition signal is described. More particularly, a GPS device is configured to receive at least one cellular acquisition signal for obtaining benefits associated with AGPS with only a small subset of AGPS circuitry to interact with a cell phone network.

摘要： A method and apparatus for mitigating interference in a satellite signal receiver is described. The satellite signal receiver receives satellite signals from a plurality of satellites. In one example, data transmission of a wireless transceiver operating in proximity to the satellite signal receiver is monitored. A control signal is transmitted to the satellite signal receiver upon occurrence of data transmission from the wireless transceiver. Signal integration within the satellite signal receiver is then gated is response to the control signal. In another example, one or more values of satellite signal samples are selected from a plurality of possible values. A percentage of satellite signal samples having the one or more selected values is monitored over a predefined period. Signal integration within the satellite signal receiver is gated in response to the percentage exceeding a predefined threshold. In yet another example, a gain setting of an automatic gain control circuit within the satellite signal receiver is adjusted in response to detection of interference.

摘要： A method of correlating a digital communications signal is described. In an example, a window is defined equal to a portion of an epoch of the digital communication signal. The digital communication signal is then correlated across the window. A determination is made as to whether a correlation peak results from the correlating. Timing parameters are then established for receiving additional digital communication signals in response to presence of the correlation peak.
