摘要： A method for validating detected code modulated signals transmitted by beacons of a positioning system and received by a receiver comprises as a first step performing measurements for the detected beacon signals. Then, at least one of the detected beacon signals is selected as a calibration signal. In a next step, at least one allowed range for results of measurements for detected beacon signals other than the calibration signal are determined based on measurements for the detected calibration signal and on an available reference position of the receiver. Finally, each detection of a beacon signal for which results of performed measurements are outside of an allowed range is rejected. The invention relates equally to a corresponding receiver, to an electronic device comprising such a receiver, to a device cooperating with such a receiver and to a corresponding positioning system.

摘要： The invention relates to the acquisition of a code modulated signal, wherein a first set of correlation results for correlations between the code modulated signal and a first replica code with different code phases and a second set of correlation results for correlations between the code modulated signal and a second replica code with different code phases are available.

Then, it is determined based on the combination whether at least one of the sets of correlation results comprises a correlation result representing the correct code phase for the first replica code or the second replica code, respectively.

摘要： A method for supporting a determination of the correlation between at least one received code modulated signal and at least one available replica code is shown. In order to reduce the total memory size required for such correlations, the method comprises storing signal samples of the at least one received code modulated signal with a first rate in a memory. The stored signal samples are then read with a second rate from the memory for determining a correlation between the read signal samples and samples of the at least one available replica code, wherein the second rate is higher than said first rate. The disclosure relates equally to a corresponding electronic device, to a chip for such an electronic device, to a system comprising such an electronic device and to a corresponding software product.

摘要： A system architecture for a receiver to process multiple signals on a common carrier frequency from a satellite. The receiver is arranged such that the receiver receives input data transmitted from the satellite. A pilot signal is tracked from the input data using a correlation channel, and a data signal is tracked from the input data using a data code generator operatively connected to the correlation channel. In one embodiment of the invention, the data signal generator creates replica code for the data signal. In another embodiment of the invention, the system can switch between the data signal generator and pilot signal generator based upon the signal-to-noise ratio of the incoming signal.

摘要： The present invention provides a method for a multi-path detection analysis and selectivity of CDMA signals using spread spectrum receivers using a correlation technique. The invention is based on determining by the spread spectrum receiver whether a distortion of a received radio frequency signal, caused by a multi-path component of said received signal, meets a predetermined condition using a pre-selected correlation analysis of said received signal. This invention is generally applicable to global navigation satellite system (GNSS) receivers and it is particularly useful in GNSS receivers, such as GPS (global positioning system) and Galileo receivers. The important goal of this invention is to provide a simple method for identifying signals that are corrupted by multi-path effects, and can be excluded from position calculation in the GNSS receivers.
